This is a stock xfs kernel rpm 1.0.2 from sgi.  No recompile, no addons
-- we are not using lvm on this machine, anyways.  Any suggestions on
how to figure out what is going on here?  Cause this is on a critical
machine and having it go down every few days is not good...

If it goes down again, is there anything I can do in kdb to help narrow
down where this is happening?
