> Memory Leak w/Temporary Queues and JMX
> --------------------------------------
>
> Key: AMQ-3938
> URL: https://issues.apache.org/jira/browse/AMQ-3938
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, JMX
> Affects Versions: 5.6.0
> Environment: Java 6
> ActiveMQ 5.6.0
> Apache Camel 2.10.0
> Network of brokers (2 nodes)
> Solaris

> I'm seeing a slow memory leak in our broker process which appears to be related to temporary queues and JMX. We had major memory leak problems before, but the 5.6.0 release fixed the majority of them. This leak seems to take about 2 weeks to fill 512MB heap but ultimately it will bring down the JVM.
>
> The process which eventually runs out of memory simply runs an embeded broker which other clients connected to it via TCP. There are a couple static Camel routes, but nothing major in this process. Other clients (connected via TCP) make heavy use of pooled connections, Apache Camel, and temporary queues for request/reply messaging.
>
> I'm still looking into the issue but I've attached a MAT memory analysis to see if anyone else has seen a related problem. It looks like the temporary queues are getting registered in JMX and never removed but I'm just guessing right now.
