----------------------------
Summary: ProtonAbstractReceiver memory leak
Key: ARTEMIS-3200
URL: https://issues.apache.org/jira/browse/ARTEMIS-3200
Project: ActiveMQ Artemis
Issue Type: Bug
Components: AMQP
Affects Versions: 2.17.0
Environment:
We were testing the new version of artemis, 2.16 and 2.17.
We are running spring integration and are using sync and async message flows
which make use of artemis. With our async message flow we encountered no
problems, but with the sync message flows we noticed the issues stated above.
Reporter: Bas
Hi,
Thanks for a wonderfull broker.
We were testing the new version of artemis, 2.16 and 2.17 and we noticed the
memory will go up during our performance tests and eventually the garbace
collector can no longer free enough memory to keep running.
We are running spring integration and are using sync and async message flows
which make use of artemis. With our async message flow we encountered no
problems, but with the sync message flows we noticed the issues stated above.
We tracked the issues by using MAT to a lambda in the class
[https://github.com/apache/activemq-artemis/blob/master/artemis-protocols/artemis-amqp-protocol/src/main/java/org/apache/activemq/artemis/protocol/amqp/proton/ProtonAbstractReceiver.java]
A largemessage cleanup action is registered through the method addClosable on
line 92. This lambda is not remembered for life cycle managment and never
de-registered. It seems we create a lot of there ProtonAbstractReceivers
through our way of messaging. And they pile up in the session. Only when we
close the session memory is freed. That we create a large nr of
ProtonAbstractReceiver might also not be correct. I doubt this because we see
no issues in our async flows. I'm not sure what these ProtonAbstractReceivers
are used for and when they are created and when not. Maybe there is a place
where I could look like some related code or some documentation.
I would like to make a unit tests and see if there is a way this can be fixed
but could someone give me a hint when this ProtonAbstracReceiver is created and
if there is already a test case resembling what I want to do so I can use that
for a quick start?
