    Default CentOS 5.2 with stuck emails and random reboots

    I'm running Zimbra 5.0.13 on CentOS 5.2 and have problems with periodic server reboots after which emails stick in the mail queue. Sometimes I can clear them by requeueing but most often I have to reboot the server. the periodic reboots began after installing Zimbra.

    I've invested a lot of my own time and have had a couple of Linux admins look at it but can't seem to find the problem. Is there an experienced Zimbra admin who would be willing to take a look at my server?

    Thanks

    That server is under the recommended specification for running Zimbra, it should be a 1.5GHZ. Randon reboots usually indicate a hardware problem, have you tried running a memory check for at least 24-48hrs?

    Do you have access to the console to see if there are any other error messages when it reboots ?

    I've run the memory test on a couple of different occasions and it has passed both times with no problems.

    Regarding the logs, there are no indications of a problem before the reboot, it simply shows the reboot.

    How long did you run it for? Memory problems don't always show unless you run them for 48hrs. What about HD problems, have you checked them?

    The memory test ran for 3-4 days and all of the hard drives are showing good.

    It has two and they came with the server so I don't know the age. Each one is fed by its own UPS
