Subject [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.
