--- Comment #3 from Denis Lambolez <denis.lambolez at gmail.com> ---
Just tested with GlusterFS 3.7.3 and the new package from André. Same
behaviour. No change. Here is the dump of the samba panic action script.
Problem is still within libgfapi.so.0. This time it seems that there is a
problem in "glfs_resolve_at".
==========================================================================
The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for PID 26859 (/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:
