conflict on port 80 shutdown the Sun Java Application Server

I have a webapplication(in JSP) running on Sun Java Application Server in Fedora Core. I set the http listener of Sun Java AppServer to port 80. so instead of accessing my application in port 8080, it is access thru port 80.

its ok for some span of time (my application is working fine) then suddenly my webapplication hungs up and the server log says that there is conflict in port 80. there is no apache (httpd) running..i dont know what causing this problem..

please help me..thanks in advance.

As root

$ netstat -pna|grep 80

find the process/program that has the port open.
