--------------------------------
Summary: Closing a connection leaks a ConnectionAdapter object
Key: QPID-5795
URL: https://issues.apache.org/jira/browse/QPID-5795
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: 0.29
Reporter: Keith Wall
Assignee: Keith Wall
We currently have a regression on trunk (0.29) whereby closure of a messaging
connection (any AMQP version) causes a ConnectionAdapter object to be leaked.
On connection close (normal or otherwise), the code fails to arrange for the
reversal of ACO#registerChild, therefore the maps ACO#_childrenByName etc
permanently retain the reference to the ConnectionAdapter. The leak is large
because this causes the sizeable IO buffers to be retained too.
This causes any long running test, that creates and closes many connections
over the lifetime of the Broker to run the risk of OOM. This problem has been
noticed owning to the failure of the long running TCK test (which has been
failing with OOM).
