> ActiveMQ broker leaks advisory topics
> -------------------------------------
>
> Key: AMQ-677
> URL: https://issues.apache.org/activemq/browse/AMQ-677
> Project: ActiveMQ
> Type: Bug
> Components: Broker
> Environment: linux, near-trunk version of ActiveMQ
> Reporter: Andrew Lusk
> Assignee: Rob Davies
> Fix For: 4.0 RC4
> Attachments: ProducerTool.java
>
>
> When I run the attached code, which AFAIK is completely legal JMS, the
> ActiveMQ broker grows to 500+ mb and crashes due to being out of heap space.
> Some investigation with hprof has lead me to believe that the advisory topics
> created by the MessageConsumers (and Producers, but I use the same producer
> each time so that's not causing a problem) are being put into a
> DestinationMap and not being removed.
> The rough origin of this is in the addProducer call in AdvisoryBroker, which
> creates the advisory topic.
> Note that this memory is not freed when the DestinationInfo removing the
> original temptopic is received, nor when the actual client exits. The object
> lifetime of these advisory destinations seems very poorly defined. If they
> are implicitly created by the server, they should be implicitly destroyed by
> the same.
> To reproduce, I've been running this code with -Dtopic=true and -Dmax=10000
> (though the problem shows up well before this amount). This is just a
> modified version of the example ProducerTool (note it doesn't actually send
> any messages).
> Please verify the correctness of the attached code.
