Description

As stated in [1] global shared durable subscriptions can cause an accumulation of subscription links in link registry. The Broker-J currently does not have any functionality for automatic removal of old links. Thus, for v7 the global shared durable subscriptions need to be disabled. If feature is required, it can be enabled but application would need to unsusbcribe from shared durable subscriptions periodically or call Virtual Host operation "purgeLinkRegistry" in order to avoid links accumulation with time.
