Message Loss in NO_ACK Mode.
----------------------------

                 Key: QPID-616
                 URL: https://issues.apache.org/jira/browse/QPID-616
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker, Java Client
    Affects Versions: M2
         Environment: Java client and broker, M2.
            Reporter: Rupert Smith
            Assignee: Rupert Smith
             Fix For: M2


The test:

./Ping-Once-Async.sh -c[8] -s[1000] -d1D ackMode=257 pubsub=true 
destinationCount=10 messageSize=5000 persistent=false transacted=false 
broker=tcp://10.0.0.1:9000 consAckMode=257 consTransacted=false 
maxPending=500000 uniqueDests=false -o no_ack_test/ -n NoAckPubSub

Jams after a while. On every message sent it increments a count, on every 
message received it decrements. A maximum count limit is set to prevent the 
test from OOMEing the broker. If messages are lost, and never received, the 
count will eventually hit its maximum value and jam the test.

Investigate possible message loss in NO_ACK mode.

Add a time-out into the test to fail it when this happens.
Add numbering of messages to the test. Messages should arrive in the order they 
are sent, so message loss should show up as a gap.
