Redhat 9 hang
Posted on 2005-03-15
I'm having problem with my server running Linux Redhat 9. The output of "uname -a" is:
Linux Premium 2.4.20-8smp #1 SMP Thu Mar 13 17:45:54 EST 2003 i686 i686 i386 GNU/Linux
It is a quad-CPU, 2G RAM clone server. The server hosts a few custom applications written by me. It hang once in a while, randomly, could be a few hours or a few weeks in between. When it hang, I can "ping" the machine, but I can't "ssh" to the server. My applications also stopped working at the same time. It will require a hard reboot to bring the server back to normal.
I've checked the /var/log/messages file but to no avail. What I can see from the file is that there's no activity when the server hang.
Can someone guide me with the troubleshooting? It looks like a hardware problem to me but I don't know how to check.
