I have a Cpanel server that is experiencing numerous apache problems…

Apache runs fine, however during the graceful restarts Cpanel does throughout the course of the day it seems to crash…

Various log examples –

I have recompiled apache and updated Cpanel to the newest RELEASE build.

I’ve modified the httpd configuration slightly since this was suggested but it hasn’t helped.

I’d really like to get this server back to having no apache outages during the day….

What happens in the apache error log when restarting via WHM ? Anything in messages ? what does service httpd configtest show ? Any chance a partition might be full ? ( df -h )

1) Nothing

2) Nothing in messages

3) Configtest says Syntax OK

4) No Partitions full

Still no luck in finding issue...I hate cpanel!

Did you install any of the addons, tomcat, mod_security, resin, etc?

These are what Apache was compiled with.

No not that, I am talking about the "addon modules" in whm

Sorry, no, no addon modules installed.

Any reason your installing 2 vulnerable php versions instead of the 1 non vulnerable one ?
I'm not sure if installing 2 versions would cause that error, but it might be.

Segmentation faults can also be caused by badly coded (php) scripts. PHP-Nuke used to be famous for them.

Also, what version of Zend is being used?
