Hypertown RedHat RHEL 5.2 Server Has Been Going Down Everyday

For the past two weeks, our Hypertown RedHat RHEL 5.2 server has been going down everyday because of a wierd Kernel Panic problem.

Attached you can see what was displayed on the console at the time of the panic. This is what SoftLayer tech. support team was able to obtain from the console.

We are not using Samba or NFS-based applications.

Here is the server's info:
