> When activemq is configured with an amqp transport and SSL, and where clients make short
lived polled connections to the queue, a slow leak exists that kills the server within about
12 hours or so (for us) with the following:
> java.lang.OutOfMemoryError: GC overhead limit exceeded
> Obtaining a heap dump in this state reveals that about 3/4 of our heap is used by the
org.apache.activemq.broker.jmx.ManagedTransportConnection as per the attached screenshots.
