Rudolf Polzer commented on QPID-978:
------------------------------------
Actually, I forgot one note...
trying to cancel the subscription, letting it automatically stop and
resubscribing will yield an exception that subscriptions have to be unique
trying to run subscriptions.stop() works and returns to the caller... however,
calling subscriptions.run() again then immediately returns, without ever
calling received(). I suppose that would be the way I am supposed to leave the
listener, but it does not work... I suppose the problem is that me using an
exception to get out of the listener causes some object not to be freed on the
server; apparently, some destructor should do that instead of relying on the
SubscriptionManager's code to free that object, or there should be a try ...
catch(...) { do that cleanup; throw; } block in the run() function of the
SubscriptionManager.

> Key: QPID-978
> URL: https://issues.apache.org/jira/browse/QPID-978
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: M2, M2.1
> Environment: Fedora 8 x86_64, qpid from redhat's package, compiled
> from qpid 2.1 sources and from svn trunk
> Reporter: Rudolf Polzer
> Assignee: Gordon Sim
> Attachments: client.cpp, server.cpp
>
>
> In a simple test program (basically, a qpid based echo server) used for
> measuring the latency of qpid, I get a severe memory leak - the 4GB RAM of
> this system are fully utilized after about two minutes.
> Also, subscriptions.stop() does not work right (subscriptions.run() then
> appears to succeed, but will never receive a packet), which is why I had to
> throw an exception to get out of the Listener after a packet was received on
> the latency measuring client. I will try to attach a test program code for
> this.
