    I have tried for days trying to overcome an issue with Litespeed. I have read every post I could find and have done everything they all said to no avail. I have a PHP script that needs to run for at least 20 minutes. I initially set the max executuion time to 3600 thinking that would do it. However, no matter what I do after about 300 seconds I get the following in the error log:

    2013-11-03 09:05:01.085 [STDERR] Killing runaway process PID: 27214 with SIGTERM

    and the web page displayed is:

    503 Service Unavailable
    The server is temporarily busy, try again later!

    I have set every remotely relevant timeout I could find in the Litespeed config to 100 times its initial value and still I get the same issue after about 300 seconds.

    Please could someone help?

    Below are my settings, and they are confirmed using phpinfo.php

    Max Connections 2000
    Max SSL Connections 500
    Connection Timeout (secs) 36000
    Max Keep-Alive Requests 32000
    Smart Keep-Alive (I have tried with this value set to No and Yes)
    Keep-Alive Timeout (secs) 60
    Initial Request Timeout (secs) 36000
    Max Idle Time 1000

    Mine is dying too on

    Killing runaway process PID: 463 with SIGTERM
    2014-03-04 09:27:07.874 [STDERR] Child process with pid: 463 was killed by signal: 15, core dump: 0

    which is super suxxx. It happens 2-3 times a day on servers with high i/o.
    And it is not just php dying, whole web server stop respongind.
    Why? Any way to avoid it?

    WHM/cPanel installed ?
    check the setting of log rotate in WHM, it may cause restart
