> Project: ActiveMQ Artemis
> Issue Type: Bug
> Reporter: Justin Bertram
> Assignee: Justin Bertram

> Fix For: 2.29.0

> Time Spent: 10m

>
> When an MQTT client subscribes to a topic the broker internally creates a
> subscription queue on the corresponding address and then creates a consumer
> on that queue to receive the messages and relay them back to the MQTT client.
> If, for some reason, adding the consumer to the queue fails then the
> subscription queue will be orphaned. It will then accumulate messages and
> consume broker resources.
