samba backtraces

[Damian Menscher]

I'd file a bug report, but I really don't have any information about a 
bug, other than two backtraces pulled from our syslog.  We're on a RHEL3 
server, running RedHat's stock samba rpm.  I don't think it ever had 
problems before we updated to their U4 patchset, which included 
samba-3.0.9-1.3E.2.  Since then, we've seen two backtraces.  Hopefully 
they're helpful to you.

We've got a dual-xeon with hyperthreading, so linux sees 4 processors. 
I don't think anything else about our server is worth mentioning.  Let 
me know if you have questions.  Also, let me know if this is a bad way 
to report backtraces, so I know if I should report future ones here 
also.
