    I'm not sure what happened but with the recent update to whm my server is being taken out by PHP eating too much memory.
    I don't really know how to zero in on what specific script is causing the problem but it's only been an issue since the update.
    I know it's not a lot to go on but anyone have any clues or at least an idea how I can narrow down the culprit?


    EDIT: Just tried to do an Easy Apache update just to make sure everything was kosher and got an out of memory error.

    edit2: According to my host Exim is the culprit

    Code:
    Aug 12 18:00:37 null kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs"
    disables this message.

    Not sure what's causing Exim to flip out but I ran /scripts/eximup --force and hope that'll do the job but if anyone has any idea why Exim would suddenly start flipping out I'd love to know.
