Description Ralph Wuerthner 2014-10-09 08:49:45 UTC 
If a SMB client is trying to submit a CREATEKEY request via RPC and the request fails due to ACCESS_DENIED, the registry is locked afterwards and any further registry updates are blocked. To unlock the registry again the client connection must be closed.

A fix is already available in master:
4237138 vl@samba.org registry: Don't leave dangling transactions

Note: this defect exists in all Samba releases
