memory exhausted problems after easy apache update

[chips12]

CENTOS 5.9 x86_64 standard – server
WHM 11.36.0 (build 14)
php 5.3.22
Apache 2.2.24

I did an easy apache update and ever since have been running into the errors shown at the end of this post. I get these errors even accessing pages with no php.

The build went ok and my websites are up, but I am getting all these errors and I am not sure if some people are having access problems or not due to this. I have searched causes for these errors, but am not finding anything that appears to be relevant in this situation.

The only problem I ran into after the build, was during a yum update there was a problem updating mod_python, I followed an instruction i read to do "yum remove mod_python" perhaps this causes a problem? I am quite stuck to find why this is happening and any advice would be appreciated.

I have updated the memory_limit in the php config from 256mb to 512mb and that does seem to have ended the memory problems for now...but I am still getting these exit segmentation faults and I am not sure why I needed to increase the memory limit as it was always ok before, unless the update affected usage somehow....
