[Tim Fox (JIRA)]

Tim Fox commented on JBMESSAGING-908:
-------------------------------------

This is easy to replicate in just a few runs, by running:

TARGET_CLASS=org.jboss.test.messaging.jms.clustering.MultipleFailoverTest
TARGET_TEST=testFailoverFloodTwoServers

And look for this

java.lang.IllegalStateException: Did not load correct number of messages

in the logs of the server that is performing failover and fails to do so

> 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.
