Messages getting dispatched in a single thread even with multiple consumer
sessions if prefetchPolicy.queuePrefetch is more than 1
----------------------------------------------------------------------------------------------------------------------------------
Key: AMQ-3657
URL: https://issues.apache.org/jira/browse/AMQ-3657
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Affects Versions: 5.5.1
Environment: Windows XP/\
\,
Reporter: Santosh Banerjee
If the prefetch limit is more than 1, ActiveMQ would tend to dispatch the
messages to a single consumer session, even though there are multiple active
consumer sessions (each with a different MessageConsumer/Listener on the same
queue) available.
So messages are getting processed sequentially in a SINGLE thread,if the
prefetch limit is > 1
But if we set the prefetch to 1 explicitly, e.g. by the following code,
concurrent processing happens as expected.
((ActiveMQConnectionFactory)connectionFactory).getPrefetchPolicy().setQueuePrefetch(1);
