Subject Re: Duplicate messages received with ActiveMQ 5.13.2
Date Tue, 25 Jul 2017 12:19:40 GMT
I can now reliably reproduce the duplication and I can prevent it. However,
the behavior leaves me a bit puzzled:

The issue is that the broker adds the message twice to the subscription, via

There is a check for duplicate messages, which only
works if is
enabled (set to true).

enableAutdit is false by default and thus I am getting duplicate messages.
However, if I add a policy that applies to the topic, then policies have which is
true by default, so any policy applied to the destination will turn audit on
and prevent duplicated messages.

I have a couple of questions:

1) Is getting duplicate messages expected behavior, if conduitSubscribers is
set to true? (i.e. when I am using

2) Why does the auditing default change when policies are applied? Or, what
is the reason that TopicSubscription has audit off by default?
