Strange event - server hung.

[speckytecky]

Came in this morning to find our fileserver (Dell T610 running 32 bit Server 2008 standard) was frozen. By that I mean it was powered, but the screen, mouse and keyboard were not responsive. Couldn't remote into it either. Forced to do a hard reboot in the end. Looking at the Event viewer revealed nothing obvious other than the server seemed to have decided by itself to shut down at 1946 hours last night. Nothing set to shut it down so it's a complete mystery. Especially why if it had some sort of instruction to shut down it had actually hung?

Memory Issue perhaps ? How are the hard disks sounding / looking ?

 

May even be a power supply problem.

 

Strange nothing in event viewer!

Hi,

 

I usually find the only thing that will force a shut down on a server is Windows updates. Did the server start up fine after you hard powered it off?

Last time this happened to a server, it turned out to be a memory module failing. I'd look at that first.

I think this may be a bigger problem than you might think.

We have had three servers across different sites with similar issues overnight.

Users complained of loss of network shares and no internet.

We found the servers whilst resounding to pings stopped servicing DHCP requests and DNS.

We had to reboot them via ILO after which they appeared to comeback online.

Still digging through log files to find out what went on?

All were HP Micro Servers!

Thanks for the replies and suggestions folks. Much appreciated.

 

I was wondering if it was an update that had kicked off the restart but no it doesn't seem to be that. Yes, post the hard restart it came back slowly but happily. So far it's been running ok the rest of the week.

 

Looking at the Event Log it was showing that it also did an unexpected restart last Sunday at 1645 hours in the afternoon. The tin hasn't been opened since it was installed close on six years ago. All 4 hard disks seem to be happy. So, memory is looking like the most likely culprit then. It's still Nader a warranty till September so call to the superb server support folk at Dell on Monday morning.

 

Thanks again you you wonderful people for your responses.

What time does the server backup and what software/service are you using to backup the server?

[speckytecky]

Backs up Wednesday evening starting at 2300 hours. Backup Exec 12.5 is the software.
