Ошибка java address already in use bind

Some times whenever I restart the application, which is built on
Java
Struts
Mysql and Jboss 4.05 Version
I get the error as Address already in use: JVM_Bind

Only fix that i know is to restart the machine and try again, it will work.
Else Some times I do Ctrl-Alt-Del and Stop all the process related to Java, some times this also works.

But what is the exact reason and how can we prevent this problem ?

On windows, in an elevated cmd/ps

net stop winnat

then

net start winnat

Resets the windows’ NAT service and that removes faulty listeners.
This method works for most ‘cannot listen on this port’ errors, like as in Docker, JVM etc.

Is it possible that MySql listening on the same port as JBoss?

Is there a port number given in the error message — something like Address already in use: JVM_Bind:8080

You can change the port in JBoss server.xml to test this.

For the sake of completeness as many may fall in this SO for other reasons than OP’s question, here is another info that saved my day :

TL;DR;
Check that the port you want to open is not reserved (even though no application has opened it)
On windows :
netsh interface ipv4 show excludedportrange protocol=tcp

Explanation :
At least on windows, another possible cause for the java.net.BindException: Address already in use: JVM_Bind is that the operating system has «reserved» the port.
If you use the commands from other answer in this topic, they will tell you that no application is listening to the port, yet you cannot open it.

Some windows update like this one reserves range port that can then no longer be claimed by processes.
Though not explicit on the port that can no longer be opened, the update note mentions a command that can help troubleshooting the issue :

netsh interface ipv4 show excludedportrange protocol=tcp

this will yield a list of port range that are blocked :

Protocol tcp Port Exclusion Ranges

Start Port    End Port
----------    --------
5357        5357
49709       49808
49809       49908
49909       50008
50009       50108
50109       50208
50280       50379

* - Administered port exclusions.

please try following options for JVM binding exception:

1. start and stop the server. and check the server process ids and kill and stop the server.
2. go to control panel->administrative tool-> service-> check all server and stop all the servers and then start your own server.
3. change the Browser which your using. for example if
   your using IE ,change it to Mozilla firefox.

I was having this problem too. For me, I couldn’t start/stop openfire (it said it was stopped, but everything was still running)

sudo /etc/init.d/openfire stop
sudo /etc/init.d/openfire start

Also, restarting apache did not help either

sudo /etc/init.d/apache2 restart

The errors were inside:

/opt/openfire/logs/stderror.log
Error creating server listener on port 5269: Address already in use
Error creating server listener on port 5222: Address already in use

The way I fixed this, I had to actually turn off the server inside the admin area for my host.

I had the same on Windows. My solution was to get which port the debug wants to connect to. (In IntelliJ a red rectangle already giving the info: «Error running Tomcat: Unable to open debugger port (127.0.0.1:XXXXX): … Already in use…»)
Let’s say XXXXX is the port number.
Then i searched for the problem and the PID in a cmd window:

netstat -ano | find "CLOSE_WAIT" | find ":XXXXX"

I got the PID number as the last number in the result line. (Let’s say YYYY)
Finally:

TASKKILL /PID YYYY

An extra info: Winscp logged out meanwhile, probably it was causing my problem.

This recently happen to me when enabling JMX on two running tomcat service within Eclipse. I mistakenly put the same port for each server.

Simply give each jmx remote a different port

Server 1

-Dcom.sun.management.jmxremote.port=9000

Server 2

-Dcom.sun.management.jmxremote.port=9001

You can try deleting the Team Server credentials, most likely those will include some kind of port in the server column.
Like https://wathever.visualstudio.com:443

Go to Windows/Preferences
expand Team then Team Foundation Server
go to Credentials and remove whichever is there.

On Mac, even when I’d search with netstat, no processes were binding to that port, but I’d still get the «Address already in use» Bind exception.

In this case, going into

Safari -> Preferences -> Privacy -> Manage Website Data… -> finding «localhost» -> Remove

fixes the problem, if there really is no process running with that port. It seems Safari’s web cache maintains a reference to the port somehow, and removing that cache frees up the port.

In Eclipse, I got this error:

run:
     [java] Error creating the server socket.
     [java] Oct 04, 2012 5:31:38 PM cascadas.ace.AceFactory bootstrap
     [java] SEVERE: Failed to create world : java.net.BindException: Address already in use: JVM_Bind
     [java] Java Result: -1
BUILD SUCCESSFUL
Total time: 10 seconds

I’m not sure why it came up now, but it ran fine just a few hours ago. Do I need to restart my machine? How do i get to the bottom of it? I appreciate any tips or advice.

For windows :

1. Find the process id

   netstat -nao | find «8080»

It will show you the process ID as a number.

Example:

TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       18856

Here 18856 is the process ID

1. Kill that process

   taskkill /PID 18856 /F

Output : SUCCESS: The process with PID 18856 has been terminated.

Here using taskkill you are killing the process ID:18856

For linux/Mac:

sudo kill -9 $(sudo lsof -t -i:8080)

Here you find the process by port 8080 using sudo lsof -t -i:8080 and killing it by sudo kill command

For those who are looking for the simplest of the answers (as that is what we usually miss), just stop your running project and start it again.
Most of the time what we do is we forget to stop the project we ran earlier and when we re-run the project it shows such an issue.

I am also attaching a photo to make it clearer (I use ‘Spring tool suite’).
So what you need to do is either click the button on the extreme right, if you want to relaunch the same project or first click on the button which is 2nd from the right to stop your project and then the button on the extreme left to run your project. I hope this will solve the issue of few of the newer programmers.

In Windows CMD line, find out the Process ID that hold a connection on the bind port by entering following command:

C:> netstat -a -o

-a show all connections

-o show process identifier

And then Terminate the process.

You need to close your port
if you are a linux user then type

fuser -k 8080/tcp

This BindException would come when another process is already running in the specified port(8080).

You can use anyone of the following approach.

1. Change the server port: If you are using Tomcat server and IntelliJ IDE, you can configure the server port by configuring the tomcat server

   

or

• Go to tomcat>conf folder
• Edit server.xml
• Search «Connector port»
• Replace «8080» by your port number
• Restart tomcat server.

1. Kill the existing running process in that port and start the server.

For Linux/Mac

sudo kill -9 $(sudo lsof -t -i:8080)

For Windows

netstat -ano | findstr :8080
taskkill /PID typeyourPIDhere /F 

Note: (/F forcefully terminates the process)

Yes, as Guido Simone said it because another process listening to the same port.If you are in Ubuntu You can simply kill that process giving command
sudo kill $(sudo lsof -t -i:[port number])

ex: sudo kill $(sudo lsof -t -i:8080)

But once it didn’t work for me.
i gave the command

$ lsof -i:[port] 

and it shows nothing.

I checked my docker containers using command
docker ps -a but non of them alive.All containers has stopped
(but i remember ,i stopped one container which was used same port few minutes ago.).To make sure that docker is not the reason,I stop whole docker process using command sudo service docker stop and try again.
Surprisingly eclipse didn’t show the error at that time .It run my program perfectly.

Hope my experience will help some one.

The port is already being used by some other process as @Diego Pino said u can use lsof on unix to locate the process and kill the respective one, if you are on windows use netstat -ano to get all the pids of the process and the ports that everyone acquires. search for your intended port and kill.

to be very easy just restart your machine , if thats possible

In my case Tomcat was running in a background. I’ve installed it as a external servlet while using Eclipse.
With a Spring Boot in Intellij it has it own server but cannot start while it’s already occupied.
In my case Tomcat starts automatically I turn on my OS, that is why I need to shut down him manualy:

$ sudo service tomcat stop

of course «tomcat» depends what version of tomcat you are using.

Hope it might help to someone.

Your port must be busy in some Other Process. So you can download TCPView on https://technet.microsoft.com/en-us/sysinternals/bb897437 and kill the process for used port.

If you don’t know your port, double click on the server that is not starting and click on Open Server Properties Page and click on glassfish from left column. You will find the ports here.

answered Aug 18, 2016 at 8:01

(1) check the port is in use or not, kill that process

$ lsof -i:[port]

(2) another reason is the port is used by ipv6, solution:

edit /etc/sysctl.conf

add this to the file

net.ipv6.conf.all.disable_ipv6 = 1

then make it effect

$ sudo sysctl -p /etc/sysctl.conf

or just reboot

It means some other process is already using the port. In case if this port is being used by some other critical applications and you don’t want to close that application, the better way is to choose any other port which is free to use.

Configure your application to use any other port which is free and you will see your application working.

You can close every Java Process and start again your app:

taskkill /F /IM java.exe

start your app again…
