[Samba] connections.tdb corruption after changing domain

[Ed Ravin]

I'm using Samba 3.0.2a on Linux, acting as a PDC.  When I change the
"workgroup = " line in smb.conf in order to change the domain being
served, I get this error whenever someone tries to connect:

  Mar 19 22:02:47 myhost smbd[6861]:   claim_connection: traverse of connections.tdb failed with error Locking error.

The client computer gets the "resources not available" error.

Deleting connections.tdb and restarting smbd fixes the problem.

Is this a problem in Samba or is something wrong with my setup?
