PC Experts - my server keeps hibernating!

[Guest Webreaper]

A real head-scratcher, this one.

I have a Dell Precision 530, twin 1.7Ghz Xeon server running XP, at home. The server runs headless, and I access it via TS from my laptop (or remotely from work). It's used as a torrent server, and also as a music server for streaming choons to my Soundbridge.

It's been running fine since I set it up a couple of months ago. To save a bit of power, and because it's noisy as hell and keeps me awake at night, I have it set up with an AT job to hibernate it at 22:30 each evening, and the BIOS wakes it up again at 8am each day. Again, that's been working just fine for the last 8 weeks.

However, last week, it suddenly started shutting down for no apparent reason. It seems to start up, works for 3-4 minutes, and then hibernates, after which it's inaccessible (remotely) until I physically power it up again (not practical when I'm in the office ).

Question is, why?!?! :rolleyes:

I've checked the event log sometimes the last thing in the event log seems to be a message saying ".NET Runtime Optimization Service (clr_optimization_v2.0.50727_32) - Completed all work. Shutting down.", which implies that this service is completing and causing the machine to shutdown or reboot. However, after some investigation it seems that the 'Shutting Down' comment refers to the CLR optimisation process, not the PC itself, so this may be a red herring. (see here: http://discussion.autodesk.com/thread.jspa?threadID=521502). I've tried uninstalling the .Net Framework v3 to see if it's that which is causing the problem, but no joy.

I've also played with the power-saving settings, to see if they'd got corrupt, but again, not change (I have them set to 'Never' hibernate). I installed AVG last night, no viruses or other crap which might be causing it.

The PC seems to stay alive when I'm connected to it, but shuts down a few minutes after I disconnect. I ran the AVG full scan, which took about half an hour, and at some point after that did the machine hibernate, so it's like it's doing it when the machine is idle.

I have no idea why it's behaving like this, but it's driving me nuts - and is particularly irritating as I'm currently trying to initial-seed a 23GB torrent at the moment, which isn't going to happen if the machine's only up for 4 minutes at a time. :D

If I disable hibernation, the machine stays awake and it's not a problem.

So, any other ideas? :P

tricky!

this link may be of help if you haven't come across it yet: http://blogs.msdn.com/davidnotario/archive.../27/412838.aspx

appears to be linked to mscorsvw.exe - which you can disable. doing this might stop the problem for you.

Thanks. I'd seen that link - and the service is already set to 'manual', so I think the whole CLR stuff is a red herring.

Any other ideas?

are you certain it's doing a hibernation? not going into standby or a full shutdown?

have you tried removing the sheduled shutdown at 10.30pm completely, to make sure that is not playing a role? also (if it _is_def. hibernating), try disabling hibernation support and see if it behaves normally then. if so try enablingit again and see if the problem comes back.
