--------------------------------------------------------------
Program that demonstrates ARTEMIS-1993 demonstrates this issue. Run the
program as described in the README.md except reduce the Xmx parameter back to
2GB (so the heap fills in a timely way), and add the
{{-XX:+HeapDumpOnOutOfMemoryError}} to {{JAVA_ARGS}} within
{{etc/artemis.profile}}. Run the program. The Broker will crash with an OOM
(heap). See attached visual vm screenshot.

> Key: ARTEMIS-2002
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2002
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: AMQP
> Affects Versions: 2.6.2
> Reporter: Keith Wall
> Priority: Major
> Attachments: ARTEMIS-2002-OOMEHeap-ProtonObjectsLeaked.png
>
>
> If an AMQP client with an attached receiving link disconnects abruptly (i.e.
> closes socket without sending the AMQP close performative), {{TransportImpl}}
> and other Proton class instances remain referenced within the heap. If many
> such clients do this, an OutOfMemoryError: Java heap space occurs. This
> occurs even though the underlying socket connection has been closed.
> I have reproduced this issue against both 2.6.2 and master
> (f0c13622ac7e821a81a354b0242ef5235b6e82df).
