FAQ
I have been testing this setup with one of our clusters and I have found an
issue where failover breaks one or two of our queues.

I have a setup where I'm running latest snapshot with Zookeeper and setup
for replicated leveldb. When I run a activemq stop (using wrapper) my active
master shutdown fine and my slave recognizes this and starts process of
going active. When I can get back into my web console I see all queues like
expected BUT there are usually one queue with 50 messages that are stuck, it
has consumers but they are not consumed. When trying to view contents of
queue with jmx or web console it just hangs and times-out. If I delete this
queue its recreated and everything starts working again.

Only log info I see are these:

2013-05-26 07:09:38,850 | WARN | Async error occurred:

Here is my env:

I tried this we the three latest Snapshots they all do the same.

(And in an unrelated error When starting latest 5.9-snapshot I get a message
that amqp is not recognized.)
