Process running but not listening

http://www.unix.com – Hello guys I am experiencing a very strange behavior on one of our AIX servers. We have an application with several processes that listen on several port numbers. Sometimes we receive complains that people cannot connect to the server on a specific port that is used by one the application processes. When we check for the process status we can see that the process is up and running and everything is ok. But when we run Code: netstat -an | grep 1234 where 1234 is (for example) the port number, we don't find the port in the list of the listening ports. The obvious solution is to kill and (HowTos)
