samba - Feb 2002 - "could not open file /var/lock/samba/unexpected.tdb"

When I start winbindd (Samba v2.2.3a on Linux), I get the entries in
log.winbindd shown below.  What's the story on all those complaints about
file "unexpected.tdb"?  There is no general problem with Samba writing
to
that subdirectory:

# ll /var/lock/samba/
total 288
-rw-r--r--    1 root     root          696 Feb 12 22:01 brlock.tdb
-rw-r--r--    1 root     root          231 Feb 13 10:15 browse.dat

-rw-r--r--    1 root     root           20 Feb 12 21:59 smbd.pid
-rw-------    1 root     root          696 Feb 12 21:59 winbindd_cache.tdb
-rw-------    1 root     root         8192 Feb 12 21:59 winbindd_idmap.tdb
-rw-r--r--    1 root     root          313 Feb 13 10:08 wins.dat

What can/should I do to stop these complaints?

Thanks.
