1. man top. Check apache processes.

2. Make sure that cpanel updates haven't turned off server side sorting in
SquirrelMail

3. Make sure that dns and indent services work on web server. uw checks
client's reverse dns address and indent by default.

4. Check session directory usage

5. If you use imapproxy, check proxy debugging options.
