Package: samba
Version: 3.0.22-1
Severity: important
I know that similar bugs have been reported, but I have not found a
way to solve this. I kept getting emails with subject "Segfault in
Samba" and have installed samba-dbg as requested. I even upgraded all
the packages in my unstable box.
I'll provide the panic email, /var/log/samba/log.smbd, and
/etc/samba/smb.conf below. If you need extra information, please let
me know. Thanks.
-------------------------
This is one of the panic emails I got after installing samba-dbg.

The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for pid 16445 (/usr/sbin/smbd).
Below is a backtrace for this process generated with gdb, which shows
the state of the program at the time the error occurred.
If the problem persists, you are encouraged to first install the
samba-dbg package which contains the debugging symbols for samba
binaries. Then submit the provided information as a bug report to Debian.
For information about the procedure for submitting bug reports , please see
http://www.debian.org/Bugs/Reporting or the reportbug(1) manpage.

Well, unfortunately, the only theories I have to explain this are either
incorrect removal of files from /var/run/samba plus a wedged smbd process
that didn't actually die before when you tried to kill it (not something we
can check for very successfully now), or very bad kernel filesystem problems
that were preventing you from creating new files under /var/run/samba...
Neither is particularly debuggable as a samba problem, and your own problem
seems to be resolved now, so I think I'm going to go ahead and close this
bug report.
Thanks,
