Need some help resolving Tomcat Java Error (Unrecognized Windows Sockets error: 0: JVM_Bind)

I am trying to run a web application on Tomcat 5. Getting a java.net.SocketException. Google search seemed to indicate that this may be due to another application using a port that Tomcat server is trying to use. I changed the port to 50000 range, and still get the same error:

Mon Jul 19 16:53:00 CDT 2010: Starting to listen to port 50002

Looks like it could be Quartz-related. Can you reboot the box and try again?

@chej: I tried that. did not help.

@objects: Correct, the catalog.engine is opening the port. I changed the limits from 3000-50000 (randomly), but the same error.

This works on another server we have deployed (same catalog.engine). I am unable to point out where the server config is going wrong.

@objects: I did verify there is only one engine started.
