Summary: HA memory leak in primary broker when overwriting
messages in a ring queue
Key: QPID-7150
URL: https://issues.apache.org/jira/browse/QPID-7150
Project: Qpid
Issue Type: Bug
Components: C++ Clustering
Affects Versions: 0.32
Reporter: Alan Conway

HA memory leak in primary broker when overwriting messages in a ring queue
ReplicatingSubscription accumulates IDs of dequeued messages to send on
dispatch. It should clear the accumulated IDs once sent. Due to a merge error,
since:
014f0f3 QPID-4327: HA TX transactions: basic replication.
The ID set is not cleared, causing it to accumulate memory slowly.
This leak would be particularly noticeable on a busy ring-queue since a
ring-queue generates a dequeue event for every enqueue once it reaches its max
size.
