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.
