Description of problem:
This is the first occurance of this in /var/log/messages and it just
continued until the next day when we could get on site and physically
power the box off.  It wouldn't even shut down cleanly after a
CTRL+ALT+DEL and the shutdown process had started and let run for 30
minutes:

Version-Release number of selected component (if applicable):
kernel-2.6.8-1.521

How reproducible:
Couldn't Reproduce

Steps to Reproduce:
1. Left the system up for a week


Actual Results:  System has yet to crash

Additional info:

FC2 was installed and the kernel updated on Sept 25th and had been up
and running without issue since that time until Nov 4th when this
error started occuring for about a 12 hour period.  We lost all
control of the box (ports would connect, but ssh wouldn't initiate,
and even console wouldn't allow for login, just kept spewing these
errors).  Since rebooting it has been fine so far.
