Marcin Giedz commented on AMQ-2657:
-----------------------------------

Hi Rob,

First of all I didn't get any notification regarding your comment so could 
react faster. But anyway... 
1. What's the option in 5.4 for garbage unused destinations ? 
2. Regarding messages types: well I'm not a programmer but we use AMQ for Order 
management System -> so we're sending "orders", "transactions" to and from 
exchanges. So rather text messages max 1k -> is there a way to "mirror" 
messages to so exactly what is being sent?
3. We have now simple script in jruby to "clean" "unconnected" temp-queues" so 
in 5.3.2 there is still this problem. I can test 5.4 if there is some relevant 
change to provide latest update if you need?

> HI,
> I tried the latest snapshot 12.03.2010, several producers and consumers. No 
> matter what I change in activemq.xml file I always end up with memorylimit 
> and broker is "frozen". However today I found one really strange thing. Maybe 
> this is something wrong with what JMX says but: several temp-queues with  
> ConsumerCount=0, ProducerCount=0 but EnqueueCount was getting up and up and 
> Dequeue was 0 all the time . This way MemoryPercentageUsage got to 100% and 
> AMQ said again something like this:
> 2010-03-16 15:02:28,455 | INFO  | Usage Manager Memory Limit reached on 
> temp-queue://e0499daa-604e-227c-57c5-8a700a83d690:0. Producers will be 
> throttled to the rate at which messages are removed from this destination to 
> prevent flooding it. See 
> http://activemq.apache.org/producer-flow-control.html for more info | 
> org.apache.activemq.broker.region.Queue | ActiveMQ Transport: 
> tcp:///127.0.0.1:46737 
> My config file is attached. All producers and consumers use CMS -3.0.1. and 
> 3.1.1.
