Filip Hanik commented on AMQ-1557:
----------------------------------
If I reconfigure the dead letter strategy
<deadLetterStrategy>
<sharedDeadLetterStrategy processExpired="false"
processNonPersistent="false" />
</deadLetterStrategy>
and turn off the flooding of the logs that it causes
log4j.logger.org.apache.activemq.broker.region.RegionBroker=ERROR
The system seems to stay up, in this case, my client (consumer) OOMs, and
during the time it OOMS, the producer freezes up again,
it seems that the producer is synchronized on a connected consumer, and there
is no asynchronicity between the two

> High message frequency causes ActiveMQ to freeze

> Key: AMQ-1557
> URL: https://issues.apache.org/activemq/browse/AMQ-1557
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.0.0, 5.1.0
> Environment: observed on Windows XP Professional SP2, Sun JDK
> 1.5.01_11, but probably affects all platforms
> Reporter: Jürgen Schumacher

> ActiveMQ freezes in a test setup with very high message frequency of
> persistent messages and multiple producers and consumers running on multiple
> machines:
> - Host 1: Multiple Producers send messages very fast to queue1
> - Host 2: Multiple Processors consume message from queue1 and send a new
> message for each consumed message to queue2, also very fast.
> - Host 3: ActiveMQ server and 1 consumer reads messages from queue2.
> With producerFlowControl enabled, the system freezes very soon (a bit more
> than 1000 messages).
> With producerFlowControl disabled, it seems to run longer at first, but it
> still freezes later.
> Using transactions or not does not seem to make a difference.
> See this thread in user mailing list for more details:

> See attachment for code of test cases and the batch files to start them.
