    I noticed weird behavior with apache on one server.

    I'm running EA3 (mpm event) on Cloudlinux 7.
    Everything was until couple days ago when I noticed (usually discovered by increase in apache load) there are where to much instances running

    $ps -aux | grep httpd

    After killall on httpd and server restart everything gets back to normal
    $killall httpd && /scripts/restartsrv_httpd

    I'm very positive this is not some temporary issue since it keeps getting back all over again for last 48hours.

    Thank you,

    Also, it seems that new httpd processes are sometimes spawn by httpd processes owned by nobody

    Hello,

    It's normal for Apache to run as the "nobody" user. It's also normal to see multiple httpd processes running on the system. The following thread is a good place to start when troubleshooting load issues:

    Troubleshooting high server loads on Linux servers

    Thank you.
