URL: https://github.com/apache/artemis/pull/6085#issuecomment-3662474783
Just a note on this. We have been testing this on our scale systems and see
that it is indeed stable. Memory and storage are not bloating and the system
has been running smoothly for 1-2 weeks.

> h1. Problem
> We are encountering memory leaks in {{PostOfficeImpl}} and
> {{PagingManagerImpl}}. We have a clustered set of nodes and use the BRIDGE
> queues to transmit messages between the nodes. We use > 10_000 topics where
> the ActiveMQServer Configuration is setup to auto-delete them. When this
> occurs the BRIDGE addresses are not purged. This causes bloating in the
> journal files and in memory. The memory issue occurs in the
> {{PagingManagerImpl.stores}} and {{PostOfficeImpl.duplicateIDCaches}} (see
> below).
> From the analysis I see these orphaned addresses need to be cleaned up. The
> periodic Reaper process needs to be augmented to achieve this.
