Firts look in /var/log/messages
Then try to understand when system crashes (what happens just before).
A ps -aux would also help you see what processes are running.

/etc/rc.config.d/savecrash

make sure the first variable is set to 1. If not set it and reboot

If it is or after next crash:

/var/adm/crash

There will e a subdirectory.

I'm attaching a cookbook on how to run q4 crash dump analysis. The only assumption I'm making is that it works on Itanium. I don't think that assumption is too big a risk.

Please ignore my post.

It does not apply to Red Hat.

Doh!

Since the Itanium systems are still pretty much at the bleeding edge you should make sure you do have all the patches as well as any relevant firmware updates installed on your system.
