问题
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 ?
回答1:
Address already in use: JVM_Bind
means that some other application is already listening on the port your current application is trying to bind.
what you need to do is, either change the port for your current application or better; just find out the already running application and kill it.
on Linux you can find the application pid by using,
netstat -tulpn

In windows this scenario happens when Eclipse crashes without a clean shutdown it will have the local Jetty or Tomcat server keep running. When you reopen Eclipse and try to start server again this will lead to the "Address already in use: JVM_Bind"
You can solve this by opening Task Manager and find the javaw.exe process and ending it.
Then you can restart the server on Eclipse.

I usually come across this when the port which the server (I use JBoss) is already in use
Usual suspects
- Apache Http Server => turn down the service if working in windows.
- IIS => stop the ISS using
- Skype =>yea I got skype attaching itself to port 80
To change the port to which JBoss 4.2.x binds itself go to:
"C:\jboss4.2.2\server\default\deploy\jboss-web.deployer\server.xml"
here default is the instance of the server change the port here :
<Connector port="8080" address="${jboss.bind.address}" >
In the above example the port is bound to 8080
回答4:
Open command line and type: netstat -a -o -n or tasklist to see currently running processes.
Find port that related to Java and type: taskkill /F /PID <your PID number>.
Click Enter.
回答5:
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.
回答6:
The quick answer on how to prevent it is that you most likely need to stop JBoss before starting it again.
You should be able to call the "Terminate" button in the Console view to shutdown the server.
回答7:
That error means that the you are trying to create a new ServerSocket on a port already in use by another ServerSocket. So try to make your application closing all sockets and connections you know about and be sure your application is completely terminated. Also check if there is another proces you launched by your program.
回答8:
It can be also caused by double definition of port 8080 in ..\tomcat\conf\server.xml :
<Connector port="8080"
enableLookups="false" redirectPort="8443" debug="0"/>
<Connector port="8080"
enableLookups="false" address="127.0.0.1" maxParameterCount="30000"/>
回答9:
please try following options for JVM binding exception:
- start and stop the server. and check the server process ids and kill and stop the server.
- go to control panel->administrative tool-> service-> check all server and stop all the servers and then start your own server.
- 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.
