[jira] [Created] (QPID-4379) HA does not properly handle expired
messages
Alan Conway created QPID-4379:
---------------------------------
Summary: HA does not properly handle expired messages
Key: QPID-4379
URL: https://issues.apache.org/jira/browse/QPID-4379
Project: Qpid
Issue Type: Bug
Components: C++ Clustering
Affects Versions: 0.18
Reporter: Alan Conway
Assignee: Alan Conway
Description of problem:
If a message expires in a queue before the HA replicator is able to browse the message, the message will be skipped and not replicated. This results in the expired message's async completion never being finalized which can stall the original source of the expired message since it will never receive a completion.
Oct 18 10:56:02 itcm24 qpidd[48819]: 2012-10-18 10:56:02 [Broker] debug Browser skipping message from 'QueueXyz'
Version-Release number of selected component (if applicable):
Qpid 0.18
How reproducible:
Frequently
Steps to Reproduce:
1. It's a race condition between a message expiring in the queue and the HA browsing subscription being able to replicate it.
Actual results:
The expired message is skipped and its async completion is never finalized.
Expected results:
While it is not truly necessary for the HA replicating subscription to replicate an expired message, the async completion needs to be finished.
