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.

If you know what port the process is running you can type: lsof -i:<port>.

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

Then kill the process with kill <pid>
