    Re: Server freezing

    Updates are applies at 12PM, Monday to Friday, if any clients miss that slot, it retries for 2 hours, then waits till the next day.

    Yes, it is a print server, the spools are stored on a different drive to the OS.

    Re: Server freezing

    I had this same problem last week, found a new print driver installed by WSUS was causing a memory leak - reverted to old 1 now no problem.

    I don't let WSUS download drivers, not changed anything to do with Printers in ages either!

    I'm keeping an eye out for mem leaks, gonna take the server offline in a few minutes and kick it about a bit!

    Re: Server freezing

    Mind, saying that, it's coming up with errors on another 1750 server that i'm not having problems with!

    Does Memtest give you false positives?

    Re: Server freezing

    No. You get false negatives sometimes because of cacheline interations hiding memory faults. Its best to disable your L1 and L2 cache's because of that when doing memtests (unless your specifically testing your L1/L2 cache memory).

    As this is a server I suggest a restore from a known good backup once the faulty memory has been replaced. You have no idea which files have been corrupted by the memory errors and written to disk with errors.

    Regarding the second server that also has memory faults, was it bought at the same time? Maybe Dell had a bad batch of ram? Do you have any other Dell machines that were purchased at the same time?

    Re: Server freezing

    Hmm, it looks like it's a problem with Memtest not knowing the server chipsets, it's coming up with errors on all 4 of our 1750's, 2 of which were bought at different times.

    It can't detect the chipset and our servers use ECC RAM, that's why I think it's coming up with the errors.

    Re: Server freezing

    It might be the memory is faulty and the ECC ram is correcting the fault most of the time (that is what ECC RAM is for afterall).

    What chipset is it?

    It's a ServerWorks® GC LE chipset, apparently!

    Suffers from some interesting MTRR bugs. Memtest wont be reliable.

    Don't buy anything with Broadcom chipsets in. They suck.

    Re: Server freezing

    I'll keep that in mind when I buy.... anything!

    Anyway, back to the problem. I don't think all 4 servers would have faulty RAM, I've not had any problems before. It's just one server that randomly breaks.

    My last option is to move the RAM from the server to a workstation with an intel chipset that supports ECC and run memtest on that to see if anything comes up!

    Re: Server freezing

    From the symptoms you describe, it definitely sounds like a memory problem, whether it's ECC or not.

    If you have 4GB physical memory I'd say (more than likely) you have 4 x 1GB memory sticks installed. Seeing as you're periodically having to take the server offline anyway, try running each stick in turn. Server 2003 SP1 should still work comfortably even with 1GB of memory.

    Re: Server freezing

    Think I'll try doing that after i've moved the RAM to a machine with an intel chipset and ran memtest on that. Cheers!
