Are you using the default ActiveMQ RA (DefaultActiveMQConnectionFactory) to send the JMS message? DefaultActiveMQConnectionFactory configures a single-pool with default max-size 10. I'm not sure whether this can explain what you saw in your scenario, but I think you can try to create a new ActiveMQ RA (you can do this via admin console) with a larger size single-pool and rerun your scenario.

Hope this helps.
