I want to start weblogic application server on port 7001, but port scan list on localhost shows a afs3-callback service occupying the port.

port state service
7001 open afs3-callback

The problem appeared after I upgraded from ubuntu 9.x to 10.04 (LTS Lucid Lynx) yesterday (I was running welogic on 7001 without any port conflict on 9.x).

I want to know how I turn off afs3-callback (or the parent process that started it) and if that will resolve the issue.
