This parameter controls the behavior of smbd 8 when given a request by a client to obtain a byte range lock on a region of an open file, and the request has a time limit associated with it. If this parameter is set and the lock range requested cannot be immediately satisfied, samba will internally queue the lock request, and periodically attempt to obtain the lock until the timeout period expires. If this parameter is set to no, then samba will behave as previous versions of Samba would and will fail the lock request immediately if the lock range cannot be obtained. yes
