[richard wood]

Package: samba Version: 3.0.22-1   ----------------Quote segfault email ---------------------- The Samba 'panic action' script, /usr/share/samba/panic-action, was called for pid 23147 (/usr/sbin/nmbd).   Below is a backtrace for this process generated with gdb, which shows the state of the program at the time the error occurred.   If the problem persists, you are encouraged to first install the samba-dbg package which contains the debugging symbols for 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) manpage.   Using host libthread_db library "/lib/libthread_db.so.1".

I do have a backup script which uses smbmount to mount a Windows XP share, backs up the mail folders and then unmounts the share.   This little script seems to leave multiple mount entries all from the Windows box & share to the same mount point.   I have tried to duplicate this unsuccessfully but I’ve only tried very briefly.   If log.nmbd is required please ask, I haven’t restarted samba since this crash.       Richard Wood
