[Pkg-samba-maint] Bug#367621: samba: Panic or segfault in Samba

[Chris Dennis]

Package: samba
Version: 3.0.23d-4
Followup-For: Bug #367621


Samba stops soon after being restarted -- and has done for a few weeks,
despite ugrading to 3.0.23d-4.  It sends me the following email (I've
installed samba-dbg as requested):
--------
The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for PID 7659 (/usr/sbin/smbd).

This means there was a problem with the program, such as a segfault.
Below is a backtrace for this process generated with gdb, which shows
the state of the program at the time the error occurred.  The Samba log
files may contain additional information about the problem.

If the problem persists, you are encouraged to first install the
samba-dbg package, which contains the debugging symbols for the 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)
manual page.
