----------------------------------------

             Summary: Communication Timeout on Commit & Failover can lead to message loss
                 Key: ARTEMIS-1304
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1304
             Project: ActiveMQ Artemis
          Issue Type: Bug
    Affects Versions: 2.1.0
            Reporter: clebert suconic
            Assignee: clebert suconic
             Fix For: 2.2.0


There is a small window that if your server takes more than the call Timeout to activate during
a failover, the client will fail to commit with a communication exception, and there won't
be any rollbacks associated with the TX.

if the client doesn't treat the exception, the consumers may have a wrong buffer on consumers
and you may endup losing messages.

Workaround: always reconnect the session, or rollback after a failure... or set the callTimeout
> time your server would need to activate itself.

This is likely a minor issue, but I would rather fix it.
