[jira] Commented: (AMQ-1824) Single producer and multiple consumer
processes, some consumers stop getting messages.

Filip Hanik commented on AMQ-1824:
----------------------------------
The fact that consumer stopped receiving messages was caused by the "transaction has not been started error"
this was caused by the default JMS template in Spring would open and close the connection for each message.
Switching to the single connection factory where a single connection is reused works around this,
it is possible that using
TransactionAwareConnectionFactoryProxy will help out with this as well, when using Spring managed transactions

> With a single producer and multiple consumer processes using the ActiveMQResourceAdapter (inside Jencks), some consumers stop getting messages. If you look at the JMX counters inside jconsole you can see the stuck subscription's pending queue size increasing. Nearly every time this exception is thrown by one of the failing consumers:

> I've written some code to reproduce this problem. Instructions:
> 1. unpack the attached source
> 2. build with 'mvn compile package'
> 3. start with ./startAll.sh (I used cygwin) - this will start 1 producer and 3 consumer processes. These programs are pointing to tcp://localhost:62616 (you can change this in spring config file)
> Look in jconsole under subscriptions and you will probably see within 1 or 2 runs, only 2 consumers being created, or possibly 3 consumers but 1 of them with an increasing pending queue size.
