Can you add the following to the smb.conf file :
In the [global] section add :

panic action = /bin/sleep 99999

and then when this occurs attach to the frozen smbd process
with gdb. Once attached, type "bt" (backtrace) at the gdb
prompt and then mail in the backtrace. Please ensure smbd is
built with symbols.

This will help us track down and fix the bug.

Thanks,
