[Samba] tdb locking errors?

I was running a netbench performance test against Samba 3.0.11, and the test has
not been able to complete fully.

The samba logs contain lines such as this:

[2005/02/28 11:35:23, 1] smbd/service.c:make_connection_snum(645)
~  slave16 (192.168.133.116) connect to service netbench initially as user
BENCHLAB+slave16 (uid=10016, gid=10001) (pid 6599)[2005/02/28 11:41:14, 0]
tdb/tdbutil.c:tdb_log(725)
~  tdb(/var/lib/samba/locking.tdb): tdb_lock failed on list 86 ltype=0 (Resource
deadlock avoided)
[2005/02/28 11:45:48, 0] tdb/tdbutil.c:tdb_log(725)
~  tdb(/var/lib/samba/locking.tdb): tdb_lock failed on list 41 ltype=0 (Resource

[2005/02/28 11:51:15, 0] tdb/tdbutil.c:tdb_log(725)
~  tdb(/var/lib/samba/locking.tdb): tdb_lock failed on list 86 ltype=0 (Resource
deadlock avoided)

Does this mean that we need to increase some parameter? Is there a known failure
in this area, or could it be a misconfiguration of the clients?

I'll be rerunning this test with more detailed logging as I try to track this
issue down.
