Are you running SP2?
Do you get any errors in the IML?
Does the server Bluescreen or just crash? What Support Pack version are you running? Update to 8.20 if you are not.
What firmware version are you at? Upgrade to 8.40 to see if that fixes it.
Have you tried getting a crash dump to see if Microsoft can figure out the problem.

On a side note, we've had issues where a server crashes due to running W2K3 SP2 and the default version of Storport.sys on our HP servers. Try downloading KB946448 (or newer) from Microsoft. This will take a reboot.
