Artemis. Qos2 on subscription.


Hello,

We use MQTT to connect to an Apache Artemis 2.6.3 server. We want to be
subscribed on qos2 in order to be aware of the messages only once. Also, we
want to publish in qos2 in order to be sure that the message will arrive
only once.

However, after subscribing to a topic in qos2, and publishing to the same
topic on qos2, we get disconnected with the following error :

Do you have any idea about that problem and how to resolve it ?

Thanks in advance,
