jmborer created AMQ-7272:
----------------------------
Summary: Fanout transport has a memory leak
Key: AMQ-7272
URL: https://issues.apache.org/jira/browse/AMQ-7272
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Affects Versions: 5.15.9
Reporter: jmborer
When using the fanout transport we had memory leaks. Actually, the
ConnectionStateTracker class retains all ActiveMQTextMessages and are never
released.
In FanoutTransport.oneway on line 405, the command is tracked by a stateTracker
object. The latter stores it in a map in ConnectionStateTracker.processMessage
on line 541. However this map in never cleared and not used anyway by the
FanoutTransport.
It is possible to the disable the message tracking by setting it to false.
We tried a local version of the ActiveMQ Client where we set the
ConnectionStateTracker.setTrackMessages(false).
We have no more memory leaks, but are unsure about side effects. In our case,
there are none because we use JMS very simply.
