Hans Bausewein commented on AMQ-1950:
-------------------------------------
Thanks. Easier than removing all those dependencies.
I've first tested with the old installation to verify that it still fails. It
did. With 1 message and 10 messages it was OK, but when I sent 50 it got the
deadlock at 33.
With the patched 700476 I do not get a dead after sending 4 times 100 messages
at a time.
I got some " Slave broker out of sync with master: Dispatched message
(ID:...id.) was not in the pending list" messages, though.
And, I guess as a result, the number of messages on the slave queue page were
not updated to the same values as on the master.
I also have a lot of temporary queues on the slave, now.
