[OpenAFS] fileserver almost crash

[Matthew Cocker]

Hi

We have had several cases of a fileserver stopping allowing access to 
volumes. Nothing seems wrong from the logs but the only way to get 
system on line again is to restart afs (sometimes linux reset required). 
We attached to the process and core dumped (backtrace below) but I am 
not sure we got what is needed.

This appears to be a different issue to the last signal 6 issue (most 
windows clients are now updated)

Cheers

Matt
