SubjectOops #2 (2.2.5)
I have a machine (DNS Server, RH5.2 based, 2.2.5 kernel) that keeps on
crashing. I have already posted one Oops earlier today on it, here is the
most recent that just happened a few minutes ago. If anyone needs more
information, or if their is anything I can do, please let me know.

I have attached the earlier oops to this message as an attachment, in case
anyone needs that as well.
