httpd locking up the server intermittently

    After upgrading to 8.4, I'm noticing that the httpd process occasionally spikes the server load up between 50 and 90, effectively bringing it down. Whenever I bounce the httpd process, the server almost instantly becomes more responsive, which is why I think it's httpd, but it could very well be the mysqld process as well. My question is this: how can I determine which site is causing the issue? Running 'top' doesn't show any process consuming excess memory or processor, so tracking it that way isn't feasible. Any advice would be appreciated.

    You, sir, are a scholar and a gentleman. I don't care what the other guys say.

    This, combined with mytop seems to have me covered. Can you think of any other monitoring tools that are "must-haves" or even just "really-really-good-idea-to-haves".

    And hey, while I've got your attention...I know that you have SA in your repos, and I've tried installing them, but it seems it's either/or when it comes to psa-spamassassin or your spamassassin. Is it possible to take your spamassassin, and just replace the Plesk-provided binary? I mean, the one provided by Plesk doesn't even have sa-update included, and I'd certainly like to get the newest version, combined with the control panel functionality.

    Either way, thanks for the mod-top advice.

    haha, you're welcome. Nothing else out there I can think of that can compare to the utility of mod-top.

    On spamassassin, absolutely. Plesk is really using the native vendor provided spamassassin, all psa-spamassassin does is provide the web interface to it (and chmod -x /etc/init.d/spamassassin... which is annoying).

    Ok, I'm late replying because I was with my kid in the hospital.

    Now that I've gotten the sympathy vote, I'll ask the dumb clarifying question. I installed the SA package from your (ART's) repo previously, and when I did, I had both /etc/init.d/spamassassin as well as /etc/init.d/psa-spamassassin installed. I generally had them both running. If I wanted to keep Plesk's ease-of-SA-use in place but take advantage of the more recent SA build (yours), what would be the best way to accomplish that?

    Please go step-by-step and use small words, as I have a 2-year-old recovering from surgery and he's rapidly sapping my sanity. Thanks again.
