Description

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.
