Add the line:

panic action = /bin/sleep 9999999

to the [global] section of your smb.conf. Restart Samba. When it
panics again you'll be left with a sleep process whose parent is
the crashed smbd. Attach to this with gdb and get (and post) a
backtrace.

That'll help us track this down and fix it (if it isn't already
fixed).

Thanks,

Jeremy.
