Ciao a tutti, da quando ho aggiornato a samba 3.5.6 ogni tanto ricevo un
panic/segfault di samba. Per fortuna è su un server non critico ma mi
piacerebbe segnalarlo. Questo è il messaggio che mi arriva:
> The Samba 'panic action' script, /usr/share/samba/panic-action,
> was called for PID 15101 (/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)
