I was running tomcat on port 8888. I'm not sure what happened but all of a sudden tomcat seemed to crash as none of the application worked. When I tried to restart tomcat server it said port 8888 was already in use. I've tried altering the port in server.xml to port 8887 - the server starts and my (jsp) wiki works, but editing pages seems to hang and this worked fine before.
any ideas how I can free port 8888 so I can restart as was, or resolve the editing page issue?
