    My server crashed and this is the log from when it crashed. Can anyone tell me what OOM-KILLER is??? What caused the crash? I'm running PSA 9.2.3 with CentOS 5

    Not sure it is Cent OS is cause

    I also noticed in my logs the following a lot of time:
    Apr 13 11:56:38 ip-208-109-XXX-XXX spam_hook[14640]: unable to open configuration file /etc/psa/psa.conf: Permission denied

    I went in and changed the permissions on this file to 755 and that message has gone. Also, I have not had anymore OOM-KILLER crashes. BTW, the link you sent just confirms a lot of people with this error, but no solutions.

    I'll keep you posted to if the problem returns or if the change to the psa.conf fixed the problem.

    Problem fixed

    Changing permissions to 777 on the file /etc/psa/psa.conf has fixed the configuration and there have been no more crashes or OOM-KILLER messages.
