High Server Load - Please Help!

Okay, I have searched this forum and I cannot find an answer. I have even tried optimizing apache and mysql. Here are my server specs:


SERVER 1 - Web server

cPanel / PHP / Eaccelerator
Dual XEON 2.8 GHZ
2 GIG Memory
RAID 1
CentOS

SERVER 2 - MySQL

Dual XEON 2.8 GHZ
4 GIG
RAID 1
CentOS

THE PROBLEM:

The problem is server 1. This server has a mail server, name server, and http server on it.

The load at any given time is > 10. It is usually closer to 20 and sometimes going into the high 20s and beyond. This makes no sense to me. My sites are not THAT busy! The load gets high enough that I get locked out of my server. Btw, stat processing is off.

Here is the output of TOP:
