Pure Master Slave broker hangs when storage limit is reached
------------------------------------------------------------

                 Key: AMQ-2564
                 URL: https://issues.apache.org/activemq/browse/AMQ-2564
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.3.0
         Environment: Ubuntu 9.10 Desktop, Java 1.6 (build 1.6.0_16-b01)
            Reporter: Jörn Kottmann
            Priority: Minor


The pure master slave broker hangs when the storage limit is reached and dequeueing messages
from the queue is not possible.

The behavior can be reproduced with a producer which sends messages to the master broker until
the slave broker writes
 "INFO | Usage Manager Store is Full. Stopping producer (ID:karkand-51292-1263305705067-0:0:1:1)
to prevent flooding queue://TestQueue. See http://activemq.apache.org/producer-flow-control.html
for more info"
this message to the console.
To reproduce the store is full message on the slave broker maybe 2 - 3 attempts are necessary
otherwise
the messages appears on the console of the master broker.

Any attempts by a test consumer to dequeue messages fail, it just hangs.

The following information gather with JMX might be interesting:
MASTER: StorePercentUsage=99
SLAVE:    StorePercentUsage=100

The attributes for the Queue are identical on both 
brokers.
