[Samba] Tdb_fetch failed

[Lee Thao]

Just deployed samba print server.  Print jobs are going thru but getting:

Mar 11 08:11:53 printsrv smbd[2017]: [2004/03/11 08:11:53, 0]
smbd/connection.c: register_message_flags(220)
Mar 11 08:11:53 printsrv smbd[2017]:   register_message_flags: tdb_fetch
failed

Mail list archive thread said to use tdbbackup.  What good will that do?  
What should I look for in tdbbackup -v?  Should I delete those tdb
that are corrupt and restart?

Lee.
