> There should be made an enhancement in JBM clustering.
> For now the behaviour is following:
> Clustered queue is used and Session_Transacted mode is used.
> 1. cluster of 3 nodes - A - B - C
> 2. send 500 to each (db status - A:500, B:500, C:500)
> 3. disconnect B from DB (db unchanged)
> 4. read C - 1000 messages read (db status A:0, B:500, C:0) - hangs 
> 5. read A - 0 messages read (db status A:0, B:500, C:0)
> 6. connect B to DB (db status A:0, B:417, C:83)
> 7. read B - 500 messages read (db status A:0, B:0, C:0)
> In step 4. consumer received 1000 from 1500 messages from nodes A and C and there are still 500 messages left in the db.
> As an enhancement there should be that client on node C in step 4. will read all the messages from clustered queue.
> Thanks,
