Error from chokidar error enospc system limit for number of file watchers reached watch

In this post, we will see – How To Fix – “ENOSPC: System Limit for Number of File Watchers Reached”. This error can occur while developing applications in React Native, Node.js, AngularJS etc.

Error: ENOSPC: System limit for number of file watchers reached, watch -------

tail: cannot watch '/var/log/messages': No space left on device"

First thing first – ENOSPC -> Denotes that means that there is not sufficient space on the drive (or Temp folder also) to save files or for watchman to watch for all file changes that are happening. This error mostly happens in the Developer Workspaces when watching files (through grunt / gulp).

Try the below fixes and see how it goes.

Do the Primitive checks first.

Primitive Checks :

• Check what is the max no of user_watches being set currently

cat /proc/sys/fs/inotify/max_user_watches

• Check what is the max no. of inotify instances which correspond to the no. of allowed Watch Services instances.

$ cat /proc/sys/fs/inotify/max_user_instances

• If you want to be more exclusive and check who is using up the inotify watches, use below. The first column will show the no. of inotify fds (NOT the number of watches) and the second no. shows the PID of that process.

find /proc/*/fd -lname anon_inode:inotify |
cut -d/ -f3 |
xargs -I '{}' -- ps --no-headers -o '%p %U %c' -p '{}' |
uniq -c |
sort -nr

• Try the npm cache clearance

  npm cache clear 
  npm cache verify

Once the above checks are completed , you can use the below fixes to apply.

Solution :

One option is to change or increase the existing Native Watch Limit i.e. how many files a process can watch. Note that npm or a process controlled by npm keeps watching so many files.

We can take help of the Linux inotify package which is used to monitor directories, individual files or filesystem events.

We can update the max_user_watches to fix it.

The max value is 524288 and if used max, that means you will be using approx 256MB/512MB of 32-bit/64-bit kernel memory.

Each inotify watch uses 540 bytes of kernel memory on 32-bit architectures, and 1080 bytes on 64-bit architectures and Kernel memory is unswappable. Hence there is obviously a memory cost.

• Put the new max_user_watches value in the config <NEW_COUNT>. The “sysctl -w” will write this kernel parameter values to the corresponding keys under /proc/sys. This option will retain this value till next Reboot. Hence after making the changes, Test if the error is gone or not.

sudo sysctl -w fs.inotify.max_user_watches=<NEW_COUNT>

• If error is gone, then you can make this <NEW_COUNT> value permanent by adding to /etc/sysctl.conf (or a file under /etc/sysctl.d usually /etc/sysctl.d/local.conf). This means add “fs.inotify.max_user_watches=<NEW_COUNT>”.
  • Debian/RedHat system – Add to /etc/sysctl.conf file.
  • Arch Linux – Add a new file into /etc/sysctl.d/ e.g. /etc/sysctl.d/40-max-user-watches.conf

$ sudo echo "fs.inotify.max_user_watches=524288" >> /etc/sysctl.conf

• Reload systemd settings to activate the new settings. To reload systemd settings, either reboot the machine or run the following command:

$ sudo sysctl -p /etc/sysctl.conf

You can also try the additional things if the issue is not resolved till this point.

Additional 1 :

Additionally, you can also modify the below settings –

• Increase the max. no. of inotify instances. This corresponds to the no. of allowed Watch Services instances.
  • Retrieve the current value.

    $ cat /proc/sys/fs/inotify/max_user_instances

  • Generally the default value is 128. This means only 128 watches can be created. To increase the no. permanently, add the configuration to /etc/sysctl.conf:

       $ sudo echo "fs.inotify.max_user_instances=1024" >> /etc/sysctl.conf

• Reload systemd settings to activate the new settings.

  $ sudo sysctl -p /etc/sysctl.conf

Additional 2:

• Increase the open file limit.
  • Retrieve the current value

$ cat /proc/sys/fs/file-max

• To permanently increase the open file limit , add the configuration to /etc/sysctl.conf:

$ sudo echo "fs.file-max=2097152" >> /etc/sysctl.conf

• Reload systemd settings to activate the new settings.

$ sudo sysctl -p /etc/sysctl.conf

Hope this post helps to solve the error.

  npmGlobalPackages:
    create-react-app: Not Found

Steps to reproduce

1. Create a new app with create-react-app
2. Add dependencies so that the total amount of files in the project (including node_modules) is larger than the file watch limit (cat /proc/sys/fs/inotify/max_user_watches)

My project doesn’t even have many dependencies. Mostly added with npm i apollo-boost graphql react-apollo -S. And it already created three times as many files as the maximum currently allowed by the system to watch. I would expect this problem to be quite common on some systems.

Expected behavior

I am aware of the solutions provided in #2549 and #6068.

Asking users to increase the limit only pushes the problem further without resolving it. And in my opinion is a workaround for a bad design. It also provides a less than ideal user experience and unnecessarily raises the bar for newbie developers.

The npm start script should either:

1. Not watch all files in the project by default, only project files.

The script can then ask the user to restart the app after updating dependencies and show info to how to enable watching node_modules if they want to recompile automatically after updating dependencies. From my experience it’s better to restart the application after dependencies have been updated rather than rely on watch due to problems with watching and compiling source files in linked npm modules (if used of course).

1. Watch all files but detect when the amount is beyond system limits.

The script can show a warning to the user telling them there is a problem and how to resolve it, then fall back to not watching node_modules until it’s resolved. Detecting how many files is in the project is quite quick:

# time find . | wc -l
45601

real    0m0.082s
user    0m0.021s
sys     0m0.064s

1. Watch all files but there should be another script similar to start that skips watching node_modules.

Providing such a script, say quick-start, could also serve as a quick example how to exclude certain folders from the watcher should the user opt to do that.

In any case the scripts documentation and/or troubleshooting and/or Advanced Configuration guide should mention that the start script will attempt to automatically watch all files in the project, including node_modules. Then it should be documented how to enable or disable (depending on what’s the default behaviour) watching specific folders, including how to enable or disable watching node_modules.

Actual behavior

Application doesn’t start. Only a cryptic error is shown to the user. For less advanced users it’s not possible to figure out what the problem might be without searching the internet and learning all the theory about inotify, kqueue (FreeBSD or Mac) and system limits. They may try various snippets of code available on Stack Overflow or other resources to increase the system limit, which may or may not work due to differences between systems.

User limit of inotify watches reached on Ubuntu 16.04

I just installed Ubuntu 16.04 and I get this warning when I start SmartGit:

Moreover I get this warning launching tail -f :

I never get this error with Ubuntu 14.04 and applications and files I’m using on the new Ubuntu are quite the same I was using in the previous version.

The only relevant differences are that I added an additional Hard Disk on the PC and I configured the Ubuntu’s backup tool. Can this problem be related with a second disk or with the backup tool?

The current default on Xenial is 8192 (see fs/notify/inotify/inotify_user.c in the kernel source), you can verify this by printing the file to stdout:

You can bump the number up, for example, doubling this to 16384, using:

bear in mind that inotify watches do consume memory, I think it’s around 160 bytes per watch on 64 bit systems.

To set this permanently, add an entry to /etc/sysctl.conf, for example:

..or manually edit /etc/sysctl.conf (you need root privileges to update it) and then run sudo sysctl -p

Above answers work great but it does not explain why which I was looking around to here my attempt for a complete answer —

Why?

Programs that sync files such as dropbox, git etc use inotify to notice changes to the file system. The limit can be see by —

For me, it shows 100000. When this limit is not enough to monitor all files inside a directory it throws this error.

Increasing the amount of inotify watchers(Short version):

If you are running Debian, RedHat, or another similar Linux distribution, run the following in a terminal:

If you are running ArchLinux, run the following command instead (see here for why):

Then paste it in your terminal and press on enter to run it.

Technical details:

Listen uses inotify by default on Linux to monitor directories for changes. It’s not uncommon to encounter a system limit on the number of files you can monitor. For example, Ubuntu Lucid’s (64bit) inotify limit is set to 8192.

You can get your current inotify file watch limit by executing:

When this limit is not enough to monitor all files inside a directory, the limit must be increased for Listen to work properly.

You can set a new limit temporary with:

If you like to make your limit permanent, use:

You may also need to pay attention to the values of max_queued_events and max_user_instances if Listen keeps on complaining.

Error: ENOSPC: System limit for number of file watchers reached angular

I am getting this error while doing my Angular 10 project.

Error from chokidar (/myProject): Error: ENOSPC: System limit for number of file watchers reached, watch ‘/myProject/tsconfig.spec.json’

Is there a method to resolve this error?

You’re running into a kernel limit with your inotify watchers. You can run this to fix it for the current boot,

You can run this to fix it for future boots,

I found this post and helped me to solve that problem. All you have to do is change the max_user_watches

I got this in vs code when doing ssh. I think the problem was that vs code was watching all the files in my node_modules folder. To solve this in vs code I went to:

File > Preferences > Settings, and then to the little paper icon at the top of the settings page. This takes you to the settings.json file vs code uses. Then I added this to the settings file and it solved the problem:

To increase the number of watches by your system

# insert the new value into the system config

# check new value was applied

How To Fix – Error “ENOSPC: System Limit for Number of File Watchers Reached” ?

How To Fix – Error “ENOSPC: System Limit for Number of File Watchers Reached” ?

In this post, we will see – How To Fix – “ENOSPC: System Limit for Number of File Watchers Reached”. This error can occur while developing applications in React Native, Node.js, AngularJS etc.

First thing first – ENOSPC -> Denotes that means that there is not sufficient space on the drive (or Temp folder also) to save files or for watchman to watch for all file changes that are happening. This error mostly happens in the Developer Workspaces when watching files (through grunt / gulp).

Try the below fixes and see how it goes.

Do the Primitive checks first.

Primitive Checks :

• Check what is the max no of user_watches being set currently

• Check what is the max no. of inotify instances which correspond to the no. of allowed Watch Services instances.

• If you want to be more exclusive and check who is using up the inotify watches, use below. The first column will show the no. of inotify fds (NOT the number of watches) and the second no. shows the PID of that process.

• Try the npm cache clearance

Once the above checks are completed , you can use the below fixes to apply.

Solution :

One option is to change or increase the existing Native Watch Limit i.e. how many files a process can watch. Note that npm or a process controlled by npm keeps watching so many files.

We can take help of the Linux inotify package which is used to monitor directories, individual files or filesystem events.

We can update the max_user_watches to fix it.

The max value is 524288 and if used max, that means you will be using approx 256MB/512MB of 32-bit/64-bit kernel memory.

Each inotify watch uses 540 bytes of kernel memory on 32-bit architectures, and 1080 bytes on 64-bit architectures and Kernel memory is unswappable. Hence there is obviously a memory cost.

• Put the new max_user_watches value in the config . The “sysctl -w” will write this kernel parameter values to the corresponding keys under /proc/sys. This option will retain this value till next Reboot. Hence after making the changes, Test if the error is gone or not.

• If error is gone, then you can make this value permanent by adding to /etc/sysctl.conf (or a file under /etc/sysctl.d usually /etc/sysctl.d/local.conf). This means add “fs.inotify.max_user_watches= ”.
  • Debian/RedHat system – Add to /etc/sysctl.conf file.
  • Arch Linux – Add a new file into /etc/sysctl.d/ e.g. /etc/sysctl.d/40-max-user-watches.conf

• Reload systemd settings to activate the new settings. To reload systemd settings, either reboot the machine or run the following command:

You can also try the additional things if the issue is not resolved till this point.

Additional 1 :

Additionally, you can also modify the below settings –

Node.js: what is ENOSPC error and how to solve?

I have a problem with Node.js and uploading files to server. For uploading files to server I use this plugin. When starting file upload to the server, Node.js process crashed and show error:

The server code doesn’t run.

Run the below command to avoid ENOSPC:

For Arch Linux add this line to /etc/sysctl.d/99-sysctl.conf :

This will also persist across reboots. Technical Details Source

ENOSPC means that there is no space on the drive.

Perhaps /tmp is full? You can configure npm to use a different temp folder by setting npm config set tmp /path/to/some/other/dir , or maybe delete everything out of the /tmp folder.

Note I solved my problem in the way that described in above source. However, see Murali Krishna’s answer, which is more comprehensive.

A simple way that solve my problem was:

npm or a process controlled by it is watching too many files. Updating max_user_watches on the build node can fix it forever. For debian put the following on terminal:

If you want know how Increase the amount of inotify watchers only click on link.

Can’t take credit for this, but @grenade pointed out that npm dedupe will fix the cause (too many files) and not the symptom.

Rebooting the machine solved the problem for me. I first tried wiping /tmp/ but node was still complaining.

On Ubuntu 18.04 , I tried a trick that I used to reactivate the file watching by ionic/node, and it works also here. This could be useful for those who don’t have access to system conf files.

On Linux, this is likely to be a limit on the number of file watches.

The development server uses inotify to implement hot-reloading. The inotify API allows the development server to watch files and be notified when they change.

The default inotify file watch limit varies from distribution to distribution (8192 on Fedora). The needs of the development server often exceeds this limit.

The best approach is to try increasing the file watch limit temporarily, then making that a permanent configuration change if you’re happy with it. Note, though, that this changes your entire system’s configuration, not just node.

If you are using Linux, your project is hitting your system’s file watchers limit

To fix this, on your terminal, try:

You need to increase the inotify watchers limit for users of your system. You can do this from the command line with:

That will persist only until you reboot, though. To make this permanent, add a file named /etc/sysctl.d/10-user-watches.conf with the following contents:

After making the above (or any other) change, you can reload the settings from all sysctl configuration files in /etc with sudo sysctl —system . (On older systems you may need to use sudo sysctl -p instead.)

I sometimes get this issue when working with Visual Studio Code on my Ubuntu machine.

In my case the following workaround helps:

Stop the watcher, close Visual Studio Code, start the watcher, and open Visual Studio Code again.

In order to test the changes, I temporary set the parameter with the value 524288.

Then I proceed to validate:

And the problem was solved. In order to make it permanent, you should try to add a line in the file «/etc/sysctl.conf» and then restart the sysctl service:

I had the same problem. However, mine was coming from Webpack. Thankfully, they had a great solution on their site:

For some systems, watching many files can result in a lot of CPU or memory usage. It is possible to exclude a huge folder like node_modules using a regular expression:

File webpack.config.js

This is a problem of inotify (inode notify) in the Linux kernel, so you can resolve it by using this command:

For a temporary solution until rebooting the pc, use the following command

A permanent solution: To make this permanent, add a file named /etc/sysctl.d/10-user-watches.conf with the following contents:

After making the change, reload the settings from all sysctl configuration files in /etc with sudo sysctl -p .

It can be hard to know how much to increase the number of watchers by. So, here’s a utility to double the number of watchers:

In my case, while I’m doing the nodemon command on the Linux server, I have my Visual Studio Code open (SSH to the server). So based on Juri Sinitson’s answer, I just close Visual Studio Code and run the nodemon command again. And it works.

My nodemon command:

nodemon server.js via npm start

I think most answers given here are correct, but using the systemctl command to restart my service solved the problem for me. Check the command below:

You should follow answers such as this one:

And for latest Ubuntu versions, run sudo sysctl —system to read these settings anew.

However, in my case, my changes to these configuration files were not picked up, because I had already tweaked these settings a while ago. and forgot about it. And I had placed the conflicting configuration file in the wrong place.

According to man sysctl.d , these settings can be placed in /etc/sysctl.d/*.conf , /run/sysctl.d/*.conf and /usr/lib/sysctl.d/*.conf .

In my case I had two files:

Due to the naming convention, my older file was read last, and took precedence.
