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

             Summary: Inifinite loop on replicated LevelDB during new Master election
                 Key: AMQ-5553
                 URL: https://issues.apache.org/jira/browse/AMQ-5553
             Project: ActiveMQ
          Issue Type: Bug
          Components: activemq-leveldb-store
    Affects Versions: 5.10.0, 5.11.0
         Environment: Ubuntu 14.04 64bit
LevelDb jni 64bit

3 ActiveMq Instances
3 ZooKeeper Instances
            Reporter: Pablo Lozano
            Priority: Critical


It seems this issue AMQ-5300 or something that looks very similar is not fixed as I have been
able to replicated on Replicated Level DB and the lastest 5.11 snapshot. The levelDB corrupts
even at the point that every time I kill current master the next slave to take the position
starts doing the infinite loop. The only way to fix this is to delete the leveldb data from
all ActiveMQ instances which obviously lets me without messages. I find this issue to be quite
critical as it occurs even on graceful shut downs of ActiveMQ.

I have a attached a copy of the logs and my levelDB directory. (If all messages on the Queue
look the same is because they are, for testing purposes i send the same message over and over)
