Subject [jira] [Created] (AMQ-5080) RAR - missing messages on master slave failover
Date Mon, 03 Mar 2014 13:14:22 GMT
Gary Tully created AMQ-5080:

             Summary: RAR - missing messages on master slave failover
                 Key: AMQ-5080
             Project: ActiveMQ
          Issue Type: Bug
          Components: JCA Container
    Affects Versions: 5.9.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.10.0

With repeated failover between master and slave and mdb that consumers from A and sends to
B in a transaction we can -
a) loose some messages acked as duplicates in error
b) duplicate some messages when acks are lost in error but don't force a rollback.

A long running test that consumers/produces 20k messages with a failover every 200 messages
eventually shows up various problems. With XA recovery and async completion - there are many
code path variations.
