How do I resolve the java net BindException Address already in use JVM Bind error

Question

While using 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 and will really appreciate any suggestions please.

Answer 1

If you are aware about what port the process is running, then you can type: lsof -i:<port>.

For example, lsof -i:8080 used to list the process (pid) running on port 8080.

Following which kill the process with kill <pid>
