---------------------------------

investigate turning off producer flow control and increasing the memory available to the broker
through the systemUsage config.

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker, JMS client
>    Affects Versions: 5.2.0

>            Priority: Critical

> Over the past couple of days some of our queues get rather full because of downstream
problems. The messages start numbering in the 1000's. When that happens ActiveMQ slows way
down. I believe is slows down because we are trying to produce a message to the overloaded
queue and it's taking a long time (minutes instead of seconds). Once the overloaded queue
is emptied the problems go away.
> Our system pretty much has all the defaults.
> Note: this was not a problem before upgrading to 5.2.0
> Any ideas on what should be done?
