It has 2 ide disks in a raid1 mirror, dual processor. It is a 1u rackmount
designed for the hardware in it, so I assume the rating of the psu is up to it.
I will dig out the rating from the manual. I know there is another server
connected to the same ups, but this has dual power supplies connected to
different ups's. Current thinking is that this server is taking too much power
at times.
This server has been running fine in our office for about a year. I am going to
get this
server moved to a more beefy ups tomorrow, so I will know if this solves it.
I will look at the pattern and compare it to any disk activity. That said I was
running some very disk intensive activity today without a problem. I was
copying our web logs from one dir to another and then zipping them up. This
must be a pretty good test!

would there always be something in the event log ?
If it is software, 95% of the time you will see something. Even if it is
only a event saying recovering from bug check or preparing memory.dmp or dr.
Watson.
>This issue started at the same time we moved the hosting of this server to
another company. The engineer there has assured me that the ups is up to the
job. We also have another server on this ups which is not rebooting.
This has nothing to do with the UPS. (Unless the UPS itself is starting to
suffer some kind of failure.)
What I mean by the power supply is the actual power supply inside the
server.
For example, we have a server that has 2 EIDE HD, 2 SCSI HD, 2 NIC cards, a
total of 3 fans all running on a 300 watt power supply.
All of a sudden, at around 11:00 PM and 4:00 AM the server would reboot.
Nothing in the logs or memory dump. After a couple of days I saw a pattern.
At 10:50 a batch file started that was doing a bunch of file updates. At
4:00 AM NAV was scheduled to do a complete virus scan. Both of these are
disk intensive.
So on a whim, I changed the power supply to a 480 watt and have not had a
problem since.
That's why I was asking about what hardware do you have.
