What os the unexpected system shutdown?  Power failure?  Reset button 
after system freeze?

The filesystem didn't flush it's buffers on shutdown.  Unexpectedly, 
files are missing and/or corrupted that should be there on startup.

You need to fix this and ensure you're using a journaled file system 
with whatever option is available for the safest, most conservative 
journaling mode.

You should be able to delete /var/db/samba (plus maybe the pid file) and 
restart samba.  Samba will create any tdb files it needs like the 
initial startup.
