Did you check all of the following:
/var/logs/warn
/var/log/messages?
/var/log/localmessages
If there's nothing in any of these files, I would
suspect a CPU lock up due to overheating, or some
similar sort of hardware problem (video card hanging
the bus, etc). How's the airflow and internal
cleanliness of the physical box, and/or any rack mount
it might be inside.
Nothing but a huge gap in all those logs. The box is at a reasonable
height (desk height) in
a barely populated rack (two servers, one switch) with front and back
open. Both servers
are cold to the touch, I know that doesn't tell you the internal temp.
but I've never had an
overheat problem in an established server where the box hasn't felt hot.
Office environment,
but it was early hours of morning so unlikely to be overheating. This
box used to sit on the
floor (carpeted) for several months and didn't overheat there despite
being full of dust, now
cleaned out.
Hopefully it's a one-off. If it happens again I'll strip and rebuild the
box. Failing that I'll have
to replace the mobo etc. At least that'll give me a kick-ass workstation
and I'll put up with
an occasional reboot.
It still doesn't give me anything to tell our Ozzie colleagues.
thanks
