Justin Bertram commented on ARTEMIS-5773:
-----------------------------------------
To be clear, duplicate cache ID entries are persisted to the journal so even if
the broker is restarted (or crashes) it will still be able to detect duplicates.
I'm very curious to see your patch.
> Memory and storage leak in PostOfficeImpl and PagingManagerImpl
> ---------------------------------------------------------------
>
> Key: ARTEMIS-5773
> URL: https://issues.apache.org/jira/browse/ARTEMIS-5773
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.44.0
> Reporter: Scott Feldstein
> Priority: Major
> Attachments: storage-freed-after-patch.png

>
> 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 notes. 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.
