    Description

      If some server registered successfully on MGS, but it got an error registration reply (MGS revoking config locks timeout or other networking problems), then the server will always get -EADDRINUSE error when it try to register next time, because the server index has been occupied on MGS in the first registration.

      Current solution for above situation is to use writeconf option to force registration.

      We need to get this improved and make MGS able to handle this gracefully.
