Subject: Panic or segfault in Samba
Date: Thu, 27 Nov 2008 14:51:35 +0100 (CET)
From: root at Heimdall (root)
The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for PID 8346 (/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
Ubuntu by visiting this link:

The program is running. Quit anyway (and detach it)? (y or n) [answered Y; input not from terminal]
This was happening on Ubuntu Hardy server and continues happening in
Intrepid after an upgrade.
samba and winbind are at version 2:3.2.3-1ubuntu3.1.
Any sensible way to have a full bt?
