Following the update to 2.0.46-63, within 2 hours, Apache had spawned over 100 child processes, and they continued to spawn. After each restart of Apache, this continued to occur. After leaving it running for 2.5 hours, I had over 250 Apache child processes eating up RAM and Swap.
As a last ditch effort (after hours of research) I removed the updates (thank you yum log!), and installed the previous versions, and everything was back to normal. It now turns out that it was ok for a day, then started doing the very same thing.
The only changes I made before this problem started happening was the update, as well as changed a few mod_security rules. I have since moved everything back, and even updated mod_security, to no avail.
If anyone has any idea why this would have suddenly started happening, please let me know!

(PS as a side note, I updated PHP thinking it might have been a PHP compatibility issue. Thanks for the directions on the site scott, I now have PHP5 running perfectly!)
