>Description:
Every 20 to 30 days, the server will kernel panic. No core
dump is written, and this message appears on the console:

=20
The servers will resume normal operation after a reboot (usually
requiring an FSCK)

>How-To-Repeat:
We cannot force this to happen. It occurs every 20 to 30 days.
