This is sounding similar to the problem I have with my setup:

1. High CPU usage.

2. Can't kill IMAP.

3. Server becomes unresponsive.

I'm using CentOS 5.2 64-bit version with the latest cPanel.

So what am I missing, other than the problem nobody else is having is  
clearly something they ARE having?

Peace,
