The broker halts message delivery to selector based queue consumers when messages outside the scope of the selector accrue.
Use Case: A queue being consumed by two selector based consumers. One looking for JMSType = 'odd', and one looking for 'even'. Drive the queue with both types of messages. Remove the 'even' consumer. Expected: 'odd' messages continue to be consumed, while 'even' messages accrue in the queue Actual: 'odd' message delivery stops once the 'even' messages queue depth approaches 1000 Additional Observations: once the 'even' consumer re-attaches, delivery to the 'odd' consumer restarts. Test Environment: 5.1, 5.2.0 (Linux) Attachment: ActiveMQ junit test case which demonstrates success with non-selector based consumers (NonDiscriminatingConsumer), and failure with selector based consumers (DiscriminatingConsumer). http://www.nabble.com/file/p20939503/DiscriminatingConsumerLoadTest.java DiscriminatingConsumerLoadTest.java -- View this message in context: http://www.nabble.com/Broker-Halts-Message-Delivery-to-Selector-Based-Queue-Consumers-tp20939503p20939503.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
