CentOS release 4.6 (Final) - Kernel Oops

A server of mine has recently been suffering a “Kernel Oops”. I have been using the following link to diagnose the problem

If contains information on how to trace and log a “Kernel Oops” problem. I believe the ksysmoops utility in my case is useless, to quote the above link ‘NOTE: ksymoops is useless on 2.6.’; hence, I am stumped. I have emailed the address in the link; however, I though I'd post here as well.

The server in question is running the following:
home# uname -a

Linux <xyz> 2.6.9-55.0.9.ELsmp #1 SMP Thu Sep 27 18:27:41 EDT 2007 i686 i686 i386 GNU/Linux

home# cat /etc/redhat-release

CentOS release 4.6 (Final)
The Oops seems to occur at a random interval, but, has constant detail in the report:

home# tail -n80000 /var/log/messages  | grep  "Oops"

Mar 10 19:15:58 home kernel: Oops: 0000 [#1]
Mar 11 01:50:33 home kernel: Oops: 0000 [#1]
Mar 12 10:44:38 home kernel: Oops: 0000 [#1]
Mar 15 00:58:24 home kernel: Oops: 0000 [#1]
The detail obtained so far is:

Unable to handle kernel paging request at virtual address 00100100

printing eip:
*pde = 3584d001
Oops: 0000 [#1]

Have you tried downgrading your kernel?

I've tried the opposite. Originally the kernel version was lower and I still had the same problem, so I upgraded.
