Crash on Alpha - 4.11-STABLE

[Rob B]

Hi there,

This is the second time I've seen this crash in the past three weeks. 
I'm not sure what the root cause either.

This box is just a home server with a single NFS exported directory 
and one NFS client.  It is also a caching http proxy server for my 
home LAN (three machines).  The crash is not occurring during busy 
times for the proxy side of things, as it happened at 2:01am.
