  • I've configured a 3 node activemq cluster using this as my guide: http://activemq.apache.org/replicated-leveldb-store.html 1) Startup activemq on 1st node. 2) Startup activemq on 2nd node At this point I see a log message on the 1st node stating it was promoted to master. Next I see this Exception and am unable to connect to the broker. Each time an activemq instance is promoted to master, this exception occurs and broker is left unusable. java.io.IOException: com.google.common.base.Objects.firstNonNull(Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object; at org.apache.activemq.util.IOExceptionSupport.create(IOExceptionSupport.java:39)[activemq-client-5.10.0.jar:5.10.0] at org.apache.activemq.leveldb.LevelDBClient.might_fail(LevelDBClient.scala:552)[activemq-leveldb-store-5.10.0.jar:5.10.0] at org.apache.activemq.leveldb.LevelDBClient.replay_init(LevelDBClient.scala:657)[activemq-leveldb-store-5.10.0.jar:5.10.0] at org.apache.activemq.leveldb.LevelDBClient.start(LevelDBClient.scala:558)[activemq-leveldb-store-5.10.0.jar:5.10.0] at org.apache.activemq.leveldb.DBManager.start(DBManager.scala:648)[activemq-leveldb-store-5.10.0.jar:5.10.0] at org.apache.activemq.leveldb.LevelDBStore.doStart(LevelDBStore.scala:235)[activemq-leveldb-store-5.10.0.jar:5.10.0] at org.apache.activemq.leveldb.replicated.MasterLevelDBStore.doStart(MasterLevelDBStore.scala:110)[activemq-leveldb-store-5.10.0.jar:5.10.0] at org.apache.activemq.util.ServiceSupport.start(ServiceSupport.java:55)[activemq-client-5.10.0.jar:5.10.0] at org.apache.activemq.leveldb.replicated.ElectingLevelDBStore$$anonfun$start_master$1.apply$mcV$sp(ElectingLevelDBStore.scala:226)[activemq-leveldb-store-5.10.0.jar:5.10.0] at org.fusesource.hawtdispatch.package$$anon$4.run(hawtdispatch.scala:330)[hawtdispatch-scala-2.11-1.21.jar:1.21] at java.lang.Thread.run(Thread.java:744)[:1.7.0_51] 2014-06-12 19:02:32,350 | INFO | Stopped LevelDB[/opt/apache-activemq-5.10.0/bin/linux-x86-64/../../data/leveldb] | org.apache.activemq.leveldb.LevelDBStore | LevelDB IOException handler.
