Hi --

I'm running a server which is usually stable, but every once in a while it hangs. The server is used as a file store using NFS and to run VMware machines.

I don't see anything in /var/log/messages or elsewhere to indicate any problem or offer any clue why the system was hung.

Any suggestions where I might look for a clue?

Probably something hardware related. Bad memory, overheating, power supply, etc. I've even seen some rare cases where a bios update would fix it although it didn't make much sense for a machine to run for years, then need a firmware change.
