Error not enough space errno 12

Solve: JDK error error = 'not enough space' (Errno = 12) when compiling Android source code, Programmer All, we have been working hard to make a technical sharing website that all programmers love.

background

When compiling the Android 10 code, the OpenJDK found an error:

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(.., .., 0) failed; error='Not enough space' (errno=12)

Cause: Errno12 may occur during the process of running or compiling a large software big project, which is a large software big project (short-term memory)

Execute command firstfree -m Is there a most important thing to see if there is any swap space SWAP (this is very important)

If there is no exchange space or a small switching space, you should install the exchange space or increase space.

The following describes adding SWAP space by expanding SwapFile on Ubuntu 18.04 to solve this compilation problem.

Remarks: The following operations require superuser privileges

refer to:

  • https://blog.csdn.net/weixin_44105991/article/details/91320644
  • https://blog.csdn.net/qq_31851107/article/details/109469331

solve

Execute the command and observe if the SWAP space exists and the size:

# free -h
              total        used        free      shared  buff/cache   available
Mem:            62G         11G         49G        5.3M        800M         49G
Swap:          2.0G        790M        1.2G

# swapon -s
Filename				Type		Size	Used	Priority
/swapfile                              	file    	2097148	806584	-2

Delete swapfile (if you have previous)

If you already exist swapfile (for example: / swapfile), do the following command delete

Swapoff / swapfile #@mount swap file
rm -rf /swapfile

Execute free and swapon -s, check if there is still swap space

Create a larger swapfile

Create a 16G/swapfile：

dd if=/dev/zero of=/swapfile bs=1M count=16384

Among them, 16384 = 16 × 1024 × 1M, that is, a 16G SwapFile is created.

  • IF = Specify input file name, / dev / zero represents empty

  • Of = specified output file name

  • BS = BYTES: At the same time, set the block size of the read / output is bytes bytes.

  • Count = Blocks: This is the block size, equal to the space specified by BS.

Modify permissions

chmode 0600 /swapfile

format

mkswap /swapfile

Here, Swapfile is created

Configure the swap file (if no before)

The general system will have swapfile, but if not, you need to configure the SWAP space when the system is started:

vim /etc/fstab

In the last increase in new lines:

/swapfile   	none 		swap   		 sw 		0 		0

Start SWAP space

swapon  /swapfile

Can be implementedfree -h ; swapon -sSee Swap Space Size

### Update [pyparsing](https://pypi.org/project/pyparsing) from **2.2.0** to **2.2.2**.


<details>
  <summary>Changelog</summary>
  
  
   ### 2.2.2
   ```
   -------------------------------
- Fixed bug in SkipTo, if a SkipTo expression that was skipping to
  an expression that returned a list (such as an And), and the 
  SkipTo was saved as a named result, the named result could be 
  saved as a ParseResults - should always be saved as a string.
  Issue 28, reported by seron.

- Added simple_unit_tests.py, as a collection of easy-to-follow unit 
  tests for various classes and features of the pyparsing library. 
  Primary intent is more to be instructional than actually rigorous 
  testing. Complex tests can still be added in the unitTests.py file.

- New features added to the Regex class:
  - optional asGroupList parameter, returns all the capture groups as
    a list
  - optional asMatch parameter, returns the raw re.match result
  - new sub(repl) method, which adds a parse action calling
    re.sub(pattern, repl, parsed_result). Simplifies creating 
    Regex expressions to be used with transformString. Like re.sub,
    repl may be an ordinary string (similar to using pyparsing's 
    replaceWith), or may contain references to capture groups by group 
    number, or may be a callable that takes an re match group and 
    returns a string.
    
    For instance:
        expr = pp.Regex(r&quot;([Hh]d):s*(.*)&quot;).sub(r&quot;&lt;1&gt;2&lt;/1&gt;&quot;)
        expr.transformString(&quot;h1: This is the title&quot;)

    will return
        &lt;h1&gt;This is the title&lt;/h1&gt;

- Fixed omission of LICENSE file in source tarball, also added 
  CODE_OF_CONDUCT.md per GitHub community standards.
   ```
   
  
  
   ### 2.2.1
   ```
   -------------------------------
- Applied changes necessary to migrate hosting of pyparsing source
  over to GitHub. Many thanks for help and contributions from hugovk,
  jdufresne, and cngkaygusuz among others through this transition,
  sorry it took me so long!

- Fixed import of collections.abc to address DeprecationWarnings
  in Python 3.7.

- Updated oc.py example to support function calls in arithmetic
  expressions; fixed regex for '==' operator; and added packrat
  parsing. Raised on the pyparsing wiki by Boris Marin, thanks!

- Fixed bug in select_parser.py example, group_by_terms was not
  reported. Reported on SF bugs by Adam Groszer, thanks Adam!

- Added &quot;Getting Started&quot; section to the module docstring, to 
  guide new users to the most common starting points in pyparsing's
  API.

- Fixed bug in Literal and Keyword classes, which erroneously
  raised IndexError instead of ParseException.

### Update [newrelic](https://pypi.org/project/newrelic) from **4.2.0.100** to **4.4.1.104**.


<details>
  <summary>Changelog</summary>
  
  
   ### 4.4.1.104
   ```
   This release of the Python agent contains bug fixes.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

Bug Fixes


The creation of sampled events sometimes raised an exception in Python 3

When more events (Transaction, Transaction Error, Custom, or Span) were created than allowed per harvest period in Python 3, sometimes a TypeError: '&lt;' not supported between instances of 'dict' and 'dict' was raised. This issue has now been fixed.
   ```
   
  
  
   ### 4.4.0.103
   ```
   This release of the Python agent introduces instrumentation for Sanic, and contains bug fixes.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

Features


Add instrumentation for Sanic framework

Data is now automatically collected for applications using the Sanic framework. Data for Sanic applications will appear in both APM and Insights. Additionally, cross application tracing and distributed tracing is supported for incoming requests for Sanic applications. In addition to service maps, Sanic applications will now show the calling application in transaction traces. See the instrumented packages page for more details.


Bug Fixes


Explain plans were not generated when using psycopg2 named cursors

When using named cursors in psycopg2, the agent attempted to generate an explain plan using the same named cursor. This resulted in a syntax error when the query was issued to the database. When using the default connection and cursor factories, the agent will now execute the explain query using only unnamed cursors.
Convert bytes-like SQL statements to strings before obfuscating

If a bytes-like object is used instead of a string when making a SQL call, a traceback was seen in the logs with TypeError: cannot use a string pattern on a bytes-like object. This issue has now been fixed.
Save settings to MessageTrace objects

If an external call using an instrumented http external library (for example requests) was used within a MessageTrace, a traceback was seen in the logs with AttributeError: 'MessageTrace' object has no attribute 'settings'. This issue has now been fixed.

### Update [pytest](https://pypi.org/project/pytest) from **3.7.4** to **3.8.2**.


<details>
  <summary>Changelog</summary>
  
  
   ### 3.8.2
   ```
   =========================

Deprecations and Removals
-------------------------

- `4036 &lt;https://github.com/pytest-dev/pytest/issues/4036&gt;`_: The ``item`` parameter of ``pytest_warning_captured`` hook is now documented as deprecated. We realized only after
  the ``3.8`` release that this parameter is incompatible with ``pytest-xdist``.

  Our policy is to not deprecate features during bugfix releases, but in this case we believe it makes sense as we are
  only documenting it as deprecated, without issuing warnings which might potentially break test suites. This will get
  the word out that hook implementers should not use this parameter at all.

  In a future release ``item`` will always be ``None`` and will emit a proper warning when a hook implementation
  makes use of it.



Bug Fixes
---------

- `3539 &lt;https://github.com/pytest-dev/pytest/issues/3539&gt;`_: Fix reload on assertion rewritten modules.


- `4034 &lt;https://github.com/pytest-dev/pytest/issues/4034&gt;`_: The ``.user_properties`` attribute of ``TestReport`` objects is a list
  of (name, value) tuples, but could sometimes be instantiated as a tuple
  of tuples.  It is now always a list.


- `4039 &lt;https://github.com/pytest-dev/pytest/issues/4039&gt;`_: No longer issue warnings about using ``pytest_plugins`` in non-top-level directories when using ``--pyargs``: the
  current ``--pyargs`` mechanism is not reliable and might give false negatives.


- `4040 &lt;https://github.com/pytest-dev/pytest/issues/4040&gt;`_: Exclude empty reports for passed tests when ``-rP`` option is used.


- `4051 &lt;https://github.com/pytest-dev/pytest/issues/4051&gt;`_: Improve error message when an invalid Python expression is passed to the ``-m`` option.


- `4056 &lt;https://github.com/pytest-dev/pytest/issues/4056&gt;`_: ``MonkeyPatch.setenv`` and ``MonkeyPatch.delenv`` issue a warning if the environment variable name is not ``str`` on Python 2.

  In Python 2, adding ``unicode`` keys to ``os.environ`` causes problems with ``subprocess`` (and possible other modules),
  making this a subtle bug specially susceptible when used with ``from __future__ import unicode_literals``.



Improved Documentation
----------------------

- `3928 &lt;https://github.com/pytest-dev/pytest/issues/3928&gt;`_: Add possible values for fixture scope to docs.
   ```
   
  
  
   ### 3.8.1
   ```
   =========================

Bug Fixes
---------

- `3286 &lt;https://github.com/pytest-dev/pytest/issues/3286&gt;`_: ``.pytest_cache`` directory is now automatically ignored by Git. Users who would like to contribute a solution for other SCMs please consult/comment on this issue.


- `3749 &lt;https://github.com/pytest-dev/pytest/issues/3749&gt;`_: Fix the following error during collection of tests inside packages::

      TypeError: object of type 'Package' has no len()


- `3941 &lt;https://github.com/pytest-dev/pytest/issues/3941&gt;`_: Fix bug where indirect parametrization would consider the scope of all fixtures used by the test function to determine the parametrization scope, and not only the scope of the fixtures being parametrized.


- `3973 &lt;https://github.com/pytest-dev/pytest/issues/3973&gt;`_: Fix crash of the assertion rewriter if a test changed the current working directory without restoring it afterwards.


- `3998 &lt;https://github.com/pytest-dev/pytest/issues/3998&gt;`_: Fix issue that prevented some caplog properties (for example ``record_tuples``) from being available when entering the debugger with ``--pdb``.


- `3999 &lt;https://github.com/pytest-dev/pytest/issues/3999&gt;`_: Fix ``UnicodeDecodeError`` in python2.x when a class returns a non-ascii binary ``__repr__`` in an assertion which also contains non-ascii text.



Improved Documentation
----------------------

- `3996 &lt;https://github.com/pytest-dev/pytest/issues/3996&gt;`_: New `Deprecations and Removals &lt;https://docs.pytest.org/en/latest/deprecations.html&gt;`_ page shows all currently
  deprecated features, the rationale to do so, and alternatives to update your code. It also list features removed
  from pytest in past major releases to help those with ancient pytest versions to upgrade.



Trivial/Internal Changes
------------------------

- `3955 &lt;https://github.com/pytest-dev/pytest/issues/3955&gt;`_: Improve pre-commit detection for changelog filenames


- `3975 &lt;https://github.com/pytest-dev/pytest/issues/3975&gt;`_: Remove legacy code around im_func as that was python2 only
   ```
   
  
  
   ### 3.8.0
   ```
   =========================

Deprecations and Removals
-------------------------

- `2452 &lt;https://github.com/pytest-dev/pytest/issues/2452&gt;`_: ``Config.warn`` and ``Node.warn`` have been
  deprecated, see `&lt;https://docs.pytest.org/en/latest/deprecations.htmlconfig-warn-and-node-warn&gt;`_ for rationale and
  examples.

- `3936 &lt;https://github.com/pytest-dev/pytest/issues/3936&gt;`_: ``pytest.mark.filterwarnings`` second parameter is no longer regex-escaped,
  making it possible to actually use regular expressions to check the warning message.

  **Note**: regex-escaping the match string was an implementation oversight that might break test suites which depend
  on the old behavior.



Features
--------

- `2452 &lt;https://github.com/pytest-dev/pytest/issues/2452&gt;`_: Internal pytest warnings are now issued using the standard ``warnings`` module, making it possible to use
  the standard warnings filters to manage those warnings. This introduces ``PytestWarning``,
  ``PytestDeprecationWarning`` and ``RemovedInPytest4Warning`` warning types as part of the public API.

  Consult `the documentation &lt;https://docs.pytest.org/en/latest/warnings.htmlinternal-pytest-warnings&gt;`_ for more info.


- `2908 &lt;https://github.com/pytest-dev/pytest/issues/2908&gt;`_: ``DeprecationWarning`` and ``PendingDeprecationWarning`` are now shown by default if no other warning filter is
  configured. This makes pytest more compliant with
  `PEP-0506 &lt;https://www.python.org/dev/peps/pep-0565/recommended-filter-settings-for-test-runners&gt;`_. See
  `the docs &lt;https://docs.pytest.org/en/latest/warnings.htmldeprecationwarning-and-pendingdeprecationwarning&gt;`_ for
  more info.


- `3251 &lt;https://github.com/pytest-dev/pytest/issues/3251&gt;`_: Warnings are now captured and displayed during test collection.


- `3784 &lt;https://github.com/pytest-dev/pytest/issues/3784&gt;`_: ``PYTEST_DISABLE_PLUGIN_AUTOLOAD`` environment variable disables plugin auto-loading when set.


- `3829 &lt;https://github.com/pytest-dev/pytest/issues/3829&gt;`_: Added the ``count`` option to ``console_output_style`` to enable displaying the progress as a count instead of a percentage.


- `3837 &lt;https://github.com/pytest-dev/pytest/issues/3837&gt;`_: Added support for 'xfailed' and 'xpassed' outcomes to the ``pytester.RunResult.assert_outcomes`` signature.



Bug Fixes
---------

- `3911 &lt;https://github.com/pytest-dev/pytest/issues/3911&gt;`_: Terminal writer now takes into account unicode character width when writing out progress.


- `3913 &lt;https://github.com/pytest-dev/pytest/issues/3913&gt;`_: Pytest now returns with correct exit code (EXIT_USAGEERROR, 4) when called with unknown arguments.


- `3918 &lt;https://github.com/pytest-dev/pytest/issues/3918&gt;`_: Improve performance of assertion rewriting.



Improved Documentation
----------------------

- `3566 &lt;https://github.com/pytest-dev/pytest/issues/3566&gt;`_: Added a blurb in usage.rst for the usage of -r flag which is used to show an extra test summary info.


- `3907 &lt;https://github.com/pytest-dev/pytest/issues/3907&gt;`_: Corrected type of the exceptions collection passed to ``xfail``: ``raises`` argument accepts a ``tuple`` instead of ``list``.



Trivial/Internal Changes
------------------------

- `3853 &lt;https://github.com/pytest-dev/pytest/issues/3853&gt;`_: Removed ``&quot;run all (no recorded failures)&quot;`` message printed with ``--failed-first`` and ``--last-failed`` when there are no failed tests.

Symptoms

error=12, Cannot allocate memory (Linux)
com.atlassian.stash.exception.ServerException: An error occurred while executing an external process: java.io.IOException: error=12, Cannot allocate memory
error=12, Not enough space (Solaris)
com.atlassian.stash.exception.ServerException: An error occurred while executing an external process: error=12, Not enough space

Cause

If you received error=12, Cannot allocate memory or error=12, Not enough space, this means your system ran out of memory or swap space when Java tried to fork a process. 

The problem is inherent with the way Java allocates memory when executing processes. When Java executes a process, it must fork() then exec(). Forking creates a child process by duplicating the current process. By duplicating the current process, the new child process will request approximately the same amount of memory as its parent process, essentially doubling the memory required. However, this does not mean all the memory allocated will be used, as exec() is immediately called to execute the different code within the child process, freeing up this memory. As an example, when Stash tries to locate git, the Stash JVM process must be forked, approximately doubling the memory required by Stash.

Note that this issue is made worse by hosting multiple webapps in the same Tomcat container as Stash (which is not supported), because more memory is used by the Java process. 

Please see Forking JVM for a more detailed explanation.

Resolution

If you are hosting multiple products in the same Tomcat container as Stash, move Stash to its own Tomcat container.

For Linux, this can be resolved by enabling over-committing memory (see option 3 of Forking JVM).

For Solaris, we recommend increasing your swap space. How much swap space do you need? This will also depend on the other applications running on the same machine. We recommend allocating at least swap equal to 4 x JVM_MAXIMUM_MEMORY, or 2 x PHYSICAL RAM, whichever is larger. The JVM_MAXIMUM_MEMORY is set in your  <Stash installation directory>/bin/setenv.sh.  You can increase your swap space if you are still running out of memory.

Источник

We all know that while doing any operations on file CPU uses resources from our system. It may be memory or some I/O devices. Moreover, depending on the load of the operations, it sometimes shares heavy or graphical operations to GPUs. Now, it may be possible that the system can always fulfill the memory or I/O requirement every time. In that case, the CPU may stop its execution and wait for the fulfillment of the resources, or sometimes it may terminate the program. In this article, we will keep some light on one such issue named OsError: [errno 12] cannot allocate memory.

Oserror: [errno 12] cannot allocate memory is raised by the system when CPU won’t get enough memory resources to process pipelined operations and execute them. It may be possible that the system doesn’t have enough memory for storing intermediaries while the program is in the process. Or, it may run out of available memory due to its usage by other pipelined operations.

What is Oserror: [errno 12] cannot allocate memory?

Oserror: [errno 12] cannot allocate memory is the memory unavailability error when we run our python program, and the system does not fulfill the memory requirement. This unavailability of resources leads to the termination of our python program with the raised error Oserror: [errno 12] cannot allocate memory.

Why do I get “Oserror: [errno 12] cannot allocate memory” Error?

There is no other reason than mentioned above for the error. Any operation we perform on our computer requires some memory resources and some input/output devices. These memory resources are used to store the intermediate files or variables created while executing our program. CPU fetches these files and variables from the main memory for further execution. Now, when the system cannot save those files in the main memory due to unavailable space, it raises the given error.

[Note: The availability of Secondary memory cannot fulfill the memory requirement by default as it is much slower than main memory. This increases the throughput of the program and can be durably expensive.]

Solution to Oserror: [errno 12] cannot allocate memory

The solution to the given error is that we need to increase the system’s memory space so that it can store the intermediate files there. Now, increasing RAM memory may not be practically possible for everyone. In that case, we need to check for some other alternative.

Now, it may not be necessary to store intermediate files. We necessarily need to extend our RAM as it is not a feasible option. What we can do we create a virtual memory in our system. This virtual memory is the part of hard disk memory allocated to work as the main memory( RAM). The use of this virtual memory is that the CPU can store temporary files between the operations. The virtual memory is also called swap memory. We need to assign 64 GB of swap memory to the system so that the CPU can use it whenever there is a requirement for that. It can be a feasible option and requires no extra cost for that. The only obstacle in this process is that it is slower whenever the CPU uses this swap memory because fetching data from the main memory is faster than a hard disk.

Botocore.Exceptions.NoCredentialsError: Unable to Locate Credentials

Python subprocess.Popen “OSError: [Errno 12] Cannot allocate memory”

However, you may also get the error while using subprocess.Popen. While using the subprocess.Popen() we somehow call the fork instance, which means that we are creating a child process or subprocess, and it is going to consume the same amount of memory that is already getting consumed by the python. Now, there can be hundreds of MB of memory space required for that. Subsequently, there may be a memory shortage, and we get the error. Now, to solve the issue, there may be two options: to increase the memory space, or the second option is to write efficient code controlling the script memory.

However, to do that, we have the alternative of using vfork and posix_spawn. But maybe we don’t want to rewrite the code for the subprocess.Popen in terms of posix_spawn/vfork. In that condition, one can use a subprocess.Popen but at the beginning of the script so that the memory that will be consumed is minimum due to fewer resources, and we got the shell script. Now, we can use the shell script for our parallel processing with the lighter tasks such as free/ps/sleep, whatever else is in a loop.
