ActiveMQ with STOMP producer, multiple consumers -- ActiveMQ doesn't distribute
messages to additional consumers.
-----------------------------------------------------------------------------------------------------------------
Key: AMQ-2155
URL: https://issues.apache.org/activemq/browse/AMQ-2155
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.2.0, 5.1.0
Environment: mac osx; rails 2.1.1; ruby 1.8.6;
Reporter: Brian Moran
Using the stock ActiveMQ 5.2.0 install, with a very small producer and consumer
(see source code here:
http://groups.google.com/group/activemessaging-discuss/browse_thread/thread/0b45ae6f030a13af#)
, using client :ack mode;
Adding additional consumers to a queue results has no affect on message
distribution -- only the originally connected consumers receive the messages
UNTIL the queue is empty, or the original message consumes disconnect. One
would LIKE to be able to add additional consumers for a queue, and have the
broker distrubute messages to those consumers -- this does NOT happen in 5.1.0
and 5.2.0.
ALSO, when there are multiple consumers attached to the broker, performance can
degrade so that only one or two consumers are being sent messages. THIS may be
related, perhaps not.
ATTACHED is a dump of the STOMP TRANSPORT trace.
