> An inbalance in use of the CurrentActor stack holds 0-10 subscriptions in memory after
they are closed. Simply by opening and closing hundreds of consumers, the broker can made
to OOM. Analysis of the heap dump shows that the Threadlocal stacks used for CurrentActor
are holding the subscriptions in memory.
