MySQL on Linux fails to load server after failover -------------------------------------------------- Key: JBMESSAGING-908 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-908 Project: JBoss Messaging Issue Type: Bug Reporter: Tim Fox Assigned To: Tim Fox Priority: Critical Fix For: 1.4.0.CR1 Sometimes, after failover occurs and a server is restarted, the server start fails with: java.lang.IllegalStateException: Did not load correct number of messages, wanted:1 but got:0 at org.jboss.messaging.core.PagingChannelSupport.processReferences(PagingChannelSupport.java:591) at org.jboss.messaging.core.PagingChannelSupport.doLoad(PagingChannelSupport.java:518) at org.jboss.messaging.core.plugin.postoffice.cluster.LocalClusteredQueue.mergeIn(LocalClusteredQueue.java:243) at org.jboss.messaging.core.plugin.postoffice.cluster.DefaultClusteredPostOffice.performFailover(DefaultClusteredPostOffice.java:2169) at org.jboss.messaging.core.plugin.postoffice.cluster.DefaultClusteredPostOffice.nodeLeft(DefaultClusteredPostOffice.java:2031) at org.jboss.messaging.core.plugin.postoffice.cluster.DefaultClusteredPostOffice.access$1800(DefaultClusteredPostOffice.java:98) at org.jboss.messaging.core.plugin.postoffice.cluster.DefaultClusteredPostOffice$HandleViewAcceptedRunnable.run(DefaultClusteredPostOffice.java:2400) at EDU.oswego.cs.dl.util.concurrent.QueuedExecutor$RunLoop.run(QueuedExecutor.java:89) at java.lang.Thread.run(Thread.java:595 or similar. Analysing logs it seems this is because when the server crashed previously it did so and partially committed a transaction, i.e inserted the ref but not the message. My suspicion is that this is because the MySQL configuration being used is setup to use the non transaction myISAAM storage which has no transaction support. But this needs to be verified.
