----------------------------------------
Summary: 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
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.
