----------------------------------------

             Summary: Block clients until coordinated sequence is advanced 
after backup drop
                 Key: ARTEMIS-3703
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3703
             Project: ActiveMQ Artemis
          Issue Type: Improvement
            Reporter: Francesco Nigro
            Assignee: Domenico Francesco Bruscino


With pluggable quorum vote, if the backup connection drop, live can serve 
clients unreplicated while not yet incremented activation sequence: this can 
lead to inconsistency if the unreplicated live will crash *before* it. 

A backup with that same activation sequence can start and become live even if 
the just crashed live data is different.
