Subject [jira] [Created] (AMQ-4789) Slow leak: org.apache.activemq.broker.jmx.ManagedTransportConnection

Graham Leggett created AMQ-4789:
-----------------------------------

             Summary: Slow leak: org.apache.activemq.broker.jmx.ManagedTransportConnection
                 Key: AMQ-4789
                 URL: https://issues.apache.org/jira/browse/AMQ-4789
             Project: ActiveMQ
          Issue Type: Bug
          Components: JMX
    Affects Versions: 5.8.0
         Environment: INFO   | jvm 1    | 2013/10/07 10:17:29 | Java Runtime: Sun Microsystems
Inc. 1.6.0_24 /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre
INFO   | jvm 1    | 2013/10/07 10:17:29 |   Heap sizes: current=83008k  free=78872k  max=4190080k

            Reporter: Graham Leggett


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.
