-------------------------------------------------------------
OK, I'm going to try the systemUsage first. Here's my current config:
{panel}
<!-- The maximum about of space the broker will use before slowing
down producers -->
<systemUsage>
<systemUsage>
<memoryUsage>
<memoryUsage limit="20 mb"/>
</memoryUsage>
<storeUsage>
<storeUsage limit="1 gb" name="foo"/>
</storeUsage>
<tempUsage>
<tempUsage limit="100 mb"/>
</tempUsage>
</systemUsage>
</systemUsage>
{panel}
Switching it to:
{panel}
<memoryUsage limit="50 mb"/>
<tempUsage limit="500 mb"/>
{panel}
Hopefully that will fix the problem - will let you know shortly.

> Active MQ performance issues when there are more than 100 queue'd up messages
> -----------------------------------------------------------------------------
>
> Key: AMQ-2333
> URL: https://issues.apache.org/activemq/browse/AMQ-2333
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, JMS client
> Affects Versions: 5.2.0
> Reporter: Marcus Malcom
> 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?
