Hi, I am testing the cluster with HornetQ on JBoss5. (HornetQ2.1.2Final with JBossEAP5.1)
Grouping message delivery in the cluster stops by closing and reconnecting of the consumer when I do setting of redistribution-delay (more than 0).
Procedure that delivery stops
When a consumer is connected to routed Queue when grouping message is redistributed to other nodes, Redistributor (QueueImpl.redistributor) of routed Queue stops.
However, the grouping message gets a consumer (Redistributor) from a group consumer (QueueImpl.groups) and is going to deliver it.
it is not delivered.（Because Redistributor has stopped, the status of QueueImpl.handle() becomes BUSY. ）
And, delivery is infinitely retried.
- 28.5.1. Clustered Grouping Best Practices
"Avoid closing consumers or make sure that you always have plenty of consumers, i.e.,if you have 3 nodes have 3 consumers."
Though it is written to a user guide in this way, I think that there may be it when it is necessary what the consumer closes and to reconnect it.
Therefore I think that it is a bug that delivery stops ,and I think that the grouping message should not do redistribute fundamentally.
Temporarily, I think that "Do not set redistribution(redistribution-delay=-1)" should be written in the user guide "28.5.1. Clustered Grouping Best Practices" .
And, When grouping message is delivered,I think that it is necessary to change it not to redistribute it.
