Yes,
mem and disk check was also our first thing to do. But it happened on
different machines (1950s and 2950s), different BIOS versions and number of
NICs. The freeze situation is unrecoverable - machine replies to pings, but
did not write anything to console. You cannot SSH to it, the only thing we
could do is power down the machine. After that everything is fine.
Thanks.

we are running CentOS 5.2 Xen virtualization system with the latest

Sometimes
really means we cannot define why or when. Sometimes the machine was idle
with just one VM, sometimes quite busy with couple of VMs.
Has anybody had the same experience? If yes, any hints on how to resolve
it
or how to trace the cause?
The complete freezing of a machine like that sounds like a hardware
issue to me, most likely the memory. Does the machine unfreeze after a
while or do you have to power cycle the server when it happens ? I
would suggest running a memtest.

Hoping the problem magically goes away by ignoring it is the
microsoft approach to programming and should never be allowed.
