    Many thanks in advance for reading/helping out with this.

    Basically, one of our cPanel servers has been not playing nice for a while now. Around August-Sep last year, the server was randomly rebooting itself for no apparent reason nor did anything show up in the logs. We checked the hardware, network equipment etc all to make sure it was not a physical issue.

    Then, out of nowhere the problem disaapeared. It's been fine for 5 months now but has just resurfaced doing exactly the same thing. I've since learnt how to log kernel crashes and each time the kerenl panics and reboots itself, the following kernel dump is displayed:


    Can anyone make a conclusion about the issue? Exim? If you need any more info just ask.

    Thank you

    James

    If I had been in the same situation that you I would contact a sys admin urgently...

    Why you should wait a reply in a forum considering that your server is your business and you need it online all the time?
