[OpenAFS] Kernel panic, 1.4.2, Solaris 9

[Kevin Hildebrand]

Hello, we just had one of our fileservers go into meltdown mode, and stop 
serving data for a while.  During this time, several of our client 
machines kernel paniced repeatedly with the messages below.  The machines
continued the reboot/panic cycle until we got the fileserver back under 
control.

We have occasional meltdowns due to load or other unknown factors, but 
this is the first time I've seen widespread client panics as a result.

I have numerous crash dumps available if anyone wants to look at them or 
wants me to provide additional data.

Thanks,

Kevin
