Re: Server Shuts Down - HELP

Unless you stick a household fan blowing directly into the case it is wise
to never run most box maker systems without the case fully on as they design
airflow with the case on, not off. Now Intel designed (or just signed off
on) some great cases that when you took the case off you still had plastic
air ducts sending the airflow right to where it was needed.

As far as logging a heat event I would not take Compaq's word for it that if
it overheated you would get a log event and graceful shutdown. I'm sure
you've got some tools from them though to monitor the case temps and CPU's
so I would start there and see if you are getting any spikes during the day
that are way above normal. The CPU's should back themselves off if they
start overheating but you may want to check that your CPU's support thermal
management.

In my experience random shutdowns come from:

1. Power loss or bad power supply (duh)
2. Overheating
3. Driver conflicts (set the OS not to reboot so you can see the blue
screen)
4. Memory issues
5. Bus issues

On the memory the best bet is to make sure your memory is on the certified
list for the board or server. Drop it down to a identical pair and see if
your stable, maybe it's a conflict between the DIMMS, timing, heat,
manufacturer, etc.

Bus issues can cause a shutdown but you can usually point to an event that
causes it. Examples would be you crash during a backup where your driving a
ton of data out the PCI or in one case we had dual NICS on a PCI bus that
worked great until under load and then the bus would freak which then caused
the OS to freak (technical term instead of using the word crash, customers
hate hearing that word).
