------------------------------------
I've just been able to reproduce this locally.. should not take long to fix now.
> Apollo stops working after some time (with durable subscriptions)
> -----------------------------------------------------------------
>
> Key: APLO-210
> URL: https://issues.apache.org/jira/browse/APLO-210
> Project: ActiveMQ Apollo
> Issue Type: Bug
> Environment: apollo-99-trunk-20120519.032132-42
> Reporter: Lionel Cons
> Priority: Blocker
> Attachments: apollo.dump, apollo2.dump
>
>
> One of our applications using Apollo seems to trigger a very severe bug
> inside the broker.
> The application is very simple: a few short lived producers that send a few
> messages to a single topic, disconnect and start again after some time, plus
> one or two long lived consumers using durable subscriptions. All this works
> fine initially but after some time (15 to 30 minutes, it depends), this stops
> working and the sent messages are not received anymore.
> On the surface, the broker seems to be working fine and other clients do
> work. However, the console reports weird statistics for the topic: the
> enqueued and dispatched counters do grow while dequeued does not change.
> Worse: the broker is in a bizarre state and cannot be stopped cleanly
> ("service apollo stop" yields to "Could not stop process PID") and only "kill
> -9" can get rid of it.
> I've tried to reproduce the problem with simple scripts and I could not. I
> suspect a concurrency problem between the concurrent producers and consumers.
> I will attach a stack dump of the broker when it is in this weird state. If
> this is not enough, we can give you access to the broker the next time this
> happens.
