Web server received unexpected signal=9

Litespeed 4.0.20has problem with WHM/cpanel 11.28.87 ?

I received an alert email like this:

web server with pid=5469 received unexpected signal=9, a core file is created. A new instance of web server will be started automatically!

I have already checked the posts here:

It seems that kind of errors occur three or four times a month.And litespeed do not restart itself automatically.I had to restart httpd service myself.

Apache is not running and that error happens at random time.

can you upgrade to 4.0.20, since there are many bug fixes and improvement since 4.0.19

then do a Force Reinstall to 4.0.20 if not yet, to be sure it's the latest 4.0.20

Well I have done a force reinstall to 4.0.20.But I am sure it's already the latest 4.0.20 since last month.

The latest 4.0.20 was updated 4/13/11 which is two weeks ago. You can do manual force install (upgrade) from command line and see if that makes any difference.

just download the latest 4.0.20 package from http://www.litespeedtech.com/litespe...downloads.html, unpack the gz file and run install.sh from the expand directory. choose U(pgrade) option during install.

Check /usr/local/cpanel/logs/safeapacherestart_log to see if "Forced restart" matches the time that lshttpd being killed.

In addition, do not disable Apache from WHM. If disabled, cPanel would not try to start httpd after killing lsws (then you have to manually start lsws).
