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.

It can be also caused by double definition of port 8080 in    tomcat conf server xml     lt Connector port  8080             enableLookups  false  redirectPort  8443  debug  0   gt   lt Connector port  8080             enableLookups  false  address  127 0 0 1  maxParameterCount  30000   gt

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

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

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

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

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        lt Connector port  8080    address    jboss bind address      gt    In the above example the port is bound to 8080

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
