[Bug 1278635] Re: Panic or segfault in Samba

[Wm Lewis]

And another Panic action today. Details below.

-------------------------------------
The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for PID 24852 (/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:
