    Server hanged

    Hello,

    Its been third time since July that my server has hanged and techs had to reboot it.

    Can anyone please tell me if there is a way to find out what has caused it to hang once it was rebooted ?
    Best Regards,

    A little more info would help some.
    Do you have ssh access to the box? What do you have running on it?

    Assuming it's a *nix machine you could try looking at the various logfiles such as /var/log/messages.

    You should definitely take a look at /var/log/messages as suggested above. In addition, is this a (semi-)managed server by any chance? If so, you can probably ask the techs to take a look at the issue for you as well.

    Odds are the problem is with Apache or mySQL. Your Apche errors logs might be helpful but for the most part, once a reboot is done you lose most all of any useful information, that help determine the exact problem.

    Probable solutions are; add more more RAM and/or optimize Apache and/or mySQL.
    Last resort is to get a beefier Server or another Server, to transfer some accounts onto.

    Ask your technicians for assistance... believe me, they don't *WANT* to have to go into the server room and manually reboot your machine when it crashes, so it's in their best interest to help you.

    less is good:
    Code:
    less /var/log/messages
    less /var/log/httpd-error.log

    You can also try to check out the server memory as well as run a test on them to check out if any possibility of a bad RAM
