I think your ZooKeeper elects a master, look at the slave log: 2016-03-08 02:08:05,307 | INFO | Promoted to master | org.apache.activemq.leveldb.replicated.MasterElector | main-EventThread
However, something goes wrong, and I think it is the hostname in your persistenceAdapter: hostname="192.168.5.200" If all servers have this hostname, the slaves cannot connect, because that master is down... Each server needs its own hostname in the replicatedLevelDB configuration. At least, that is how I have it and it works like a charm. -- View this message in context: http://activemq.2283324.n4.nabble.com/Replicated-LevelDB-uses-Apache-ZooKeeper-problem-tp4709020p4715593.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
