Dear All

I am facing a problem in AIX Server. Our application is java based application. My application using some private ports(4900,4901).The ports are listening(Screen shot given below). When we start the application it is working fine.some times the ports are blocked automatically in between 1 to 7days.At that time when we checked within the AIX (local) system we are not able to telnet those ports. The ports are closing automatically. I also enter these ports in /etc/services.

My application fully tested and working on RHEL4 & 5. We are not facing any problem in Redhat Linux and also in Windows.advice possible solutions for this.

========================================================
$ netstat -Aan | grep 4901
f100060002bd8398 tcp 0 0 *.4901 *.* LISTEN
$ netstat -Aan | grep 4900
f100060001bf4398 tcp 0 0 *.4900 *.* LISTEN
========================================================

Thanks & Regards

What message do you get from telnet when the ports are "blocked"?
When the ports are blocked are the processes still running?

Java Process not running

Find out why your application is quitting and fix it.
