> Key: AMQ-6465
> URL: https://issues.apache.org/jira/browse/AMQ-6465
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, networkbridge
> Affects Versions: 5.14.1
> Reporter: Christopher L. Shannon
> Assignee: Christopher L. Shannon
> Fix For: 5.15.0, 5.14.2
>
>
> There is an issue with duplicate message suppression for durable
> subscriptions over a network bridge that is causing the memory usage counter
> to grow and never shrink. The issue is that when the message is checked
> against the network bridge filter, a reference to the message is incremented
> (which increases the memory usage counter) but then that reference is never
> decremented so the memory usage doesn't decrease as it should. The actual
> memory is freed but the counter continues to grow until it reaches the
> configured maximum at which point the broker can't do any work because it
> thinks the memory is full.
