> 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.
