HP ML350 G5 - Windows Server 2003 x64 - Reboots Without Warning

Hello Experts,

I have a remote HP server rebooting about once every 2 - 10 days. I cant seem to find out why it's rebooting, but I can see the reboots in the error log (services loading, etc). I would have to guess a BSOD or freeze is occuring, but I cant nail down what is occuring exactly.

On Windows XP clients, I can typically find the minidump files, but I cannot find any on the server. I have iLO access, and all seems relatively normal. There is a strange crash reported in the HP Management Log from a few days ago, but this was not reported this morning when the server rebooted unexpectedly.

Any good ideas on where I can look next???

Please ask for further details, but here's an idea of the server:
- HP ML350 G5
- Windows Server 2003 x64 Standard Ed.
- Kaspersky AV 6.0.2.555 w/ Critical fix 7
- Symantec Backup Exec 12
- Primary purpose: File, Printer, DHCP

Thanks!

You can set mini dump on your server. Make sure you have 4GB of pagefile on C: Check the attachment.
In the mean time, you can update the firmware on your server. I suspect it is a driver/firmware conflict on this server.

Hello,
I had it set to Kernel Memory Dump. Let me switch it and see. Do server dump files appear in %systemroot%\minidump same as XP?

For the Firmware/Support Pack, I suspected the same, and have updated recently. I will check again and verify though ~ I knew this is what HP was going to tell me too.

Server should do mini dump as XP. Don't forget you need to make sure your primary pagefile existed in C: if not, it will not dump.

OK - Thanks!
I've made some page and dump file changes.
I will also try and run a firmware update CD tonight, this looks like it's newer than the last time I ran one. Please feel free to post any other thoughts, and I'll give another update again shortly. (since it typically takes a couple days for the reboot to occur)

CD is probably out of date so don't forget the suplemental updates. Pay particular attention to hpqilo2 driver - are you getting any event id 57s?

Hello,
Yes - I believe we're close to 100% up-to-date and I've also changed the pagefile and dump settings as mentioned earlier. I'm watching it closely to see if/when the next crash occurs.

There are no 57 errors in the System event logs.
I'll keep you posted Thanks again!

Just a short update - no reboot yet - but keeping my eye on it. Thanks!

Another thing to look at is UPS. If your server connects to a UPS unit, make sure the battery is OK (green led) on the unit.

The server did reboot once during the past week. Strangly enough, there was still no minidump for the reboot. So your UPS thought could be something... Too bad this is a remote location, so I just cant check it easily.

We found that a new PSP (8.40) was released recently, and so now this is installed (and actually fixed another smaller issue). Colleagues also noticed the CPU was not playing nicely with the local SQL installation, and therefore they changed a setting in BIOS. Now the CPU is set to static high performance instead of dynamic.

We'll see if this helps.
