A-MQ 6.x can be configured to globally control the memory and disk resources used, as documented at http://activemq.apache.org/producer-flow-control.html. This is essential in our environment.

Thanks for the feedback Lionel. I've logged two corresponding requests in the RH systems as well:
Please keep us posted on your findings.
