Jörn Kottmann commented on AMQ-2564:
------------------------------------
I repeated the test with the apache-activemq-5.4-SNAPSHOT build from Wed Jan 06
15:02:31 GMT+00:00 2010 (http time stamp on the download site).
The result was the same as described above.
After stopping the slave broker it was possible to dequeue messages again from
the master broker.
The 5.4-SNAPSHOT version prints out more information to the console:

The producer was directly connected to the master broker and not the slave
broker. These messages must be about a connection between the master and slave
broker.

> 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
> Attachments: activemq-master.xml, activemq-slave.xml
>
>
> 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.
