             Summary: Serialize re-registration of DUCC services to reduce chance  of duplicate services
                 Key: UIMA-5246
                 URL: https://issues.apache.org/jira/browse/UIMA-5246
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Burn Lewis
            Assignee: Burn Lewis
             Fix For: future-DUCC


After an unregister + register ducc-mon has sometimes shown 2 service with the same endpoint.  Apparently the older unregistered one was not marked as "archived" in the DB.  Currently new instances of the service may be created before all of the old ones have been removed - would be better if the old service is completely removed before the new instances created.
Should also handle failures to update the DB.
