C Velo updated AMQ-2906:
------------------------
Environment: CentOS 5.2 (2.6.18-128.1.10.el5.xs5.5.0.51xen), ActiveMQ
server 5.4.0, ActiveMQ client 5.2.0 (w/ connection pooling) (was: CentOS 5.2
(2.6.18-128.1.10.el5.xs5.5.0.51xen), ActiveMQ server 5.4.0, ActiveMQ client
5.2.0)
> Seeing messages getting "stuck" on brokers w/o application consumers

> Key: AMQ-2906
> URL: https://issues.apache.org/activemq/browse/AMQ-2906
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.4.0
> Environment: CentOS 5.2 (2.6.18-128.1.10.el5.xs5.5.0.51xen), ActiveMQ
> server 5.4.0, ActiveMQ client 5.2.0 (w/ connection pooling)
> Reporter: C Velo
> Attachments: activemq_broker1.xml
>
>
> Seeing messages moved around between brokers and occasionally getting "stuck"
> on brokers w/o application
> consumers on it (even though the broker might have an ActiveMQ consumer
> attached to it). I can still see messages
> getting Enqueued and Dequeued on the broker containing the "stuck" messages,
> but the "stuck" messages never
> move (have some messages that have been on the queue for 1hour+).
> Current setup:
> • 3 Producers
> • 3 brokers
> • 3 Application consumers (which are using ActiveMQ connection pooling)
> • 2 application consumers --> broker1
> • 1 application consumer --> broker2
> • broker3 <-- 0 application consumers
> ----
> This is what the networkConnector string looks like in the activemq.xml file
> on the server side:
> (note: line breaks are for readability - in practice it is a single line w/o
> the "\" at the end of each line)
> {code}
> <networkConnector name="ActiveMQ Cluster"
> uri="static:(tcp://broker1:61616,tcp://broker2:61616,tcp://broker3:61616)" \
> conduitSubscriptions="true" dynamicOnly="true"
> decreaseNetworkConsumerPriority="false" \
> suppressDuplicateQueueSubscriptions="true" duplex="false"
> networkTTL="5"/>
> {code}
> ----
> This is what the broker.url string looks like in on the client side:
> (note: line breaks are for readability - in practice it is a single line w/o
> the "\" at the end of each line)
> {code}
> amq.publisher.broker.url=failover\:tcp\://broker1\:61616?wireFormat.maxInactivityDuration=0&daemon=true,\
>
> tcp\://broker2\:61616?wireFormat.maxInactivityDuration=0&daemon=true,\
>
> tcp\://broker3\:61616?wireFormat.maxInactivityDuration=0&daemon=true
> {code}
> ----
> +To reproduce:+
> * start up multiple Producers, sending messages to the 3 brokers
> * start up only 2 consumers connected to 2 of the 3 brokers.
