Description

Description of problem:
qpid trace/logs statistics about object deletion. However some of these data are wrong. In particular msgDepth for a queue is everytime zero (and msgTotalDequeues equals to msgTotalEnqueues despite no consumer was subscribed to the queue), or unackedMessages for a session is zero everytime as well.

Version-Release number of selected component (if applicable):
qpid 0.22

How reproducible:
100%

Steps to Reproduce:
1) msgDepth:0 for queue:
echo "auth=no" > /etc/qpid/qpidd.conf
echo "trace=yes" >> /etc/qpid/qpidd.conf
echo "log-to-file=/tmp/qpidd.log" >> /etc/qpid/qpidd.conf
rm -rf /var/lib/qpidd/* /tmp/qpidd.log
service qpidd restart
qpid-send -m 123 -a "testQueue;

{create:always, delete:always}

"
sleep 10 # just to let periodic processing to run & print out the stats
grep "Mgmt delete queue" /tmp/qpidd.log

Actual results:
2013-08-29 14:05:38 [Model] trace Mgmt delete queue. id:testQueue Statistics:

{acquires:123, bindingCount:0, bindingCountHigh:0, bindingCountLow:0, byteDepth:0, byteFtdDepth:0, byteFtdDequeues:0, byteFtdEnqueues:0, bytePersistDequeues:0, bytePersistEnqueues:0, byteTotalDequeues:0, byteTotalEnqueues:0, byteTxnDequeues:0, byteTxnEnqueues:0, consumerCount:0, consumerCountHigh:0, consumerCountLow:0, discardsLvq:0, discardsOverflow:0, discardsPurge:0, discardsRing:0, discardsSubscriber:0, discardsTtl:0, flowStopped:False, flowStoppedCount:0, messageLatencyAvg:0, messageLatencyCount:0, messageLatencyMax:0, messageLatencyMin:0, msgDepth:0, msgFtdDepth:0, msgFtdDequeues:0, msgFtdEnqueues:0, msgPersistDequeues:0, msgPersistEnqueues:0, msgTotalDequeues:123, msgTotalEnqueues:123, msgTxnDequeues:0, msgTxnEnqueues:0, releases:0, reroutes:0, unackedMessages:0, unackedMessagesHigh:0, unackedMessagesLow:0}

Expected results:
acquires:0
msgTotalDequeues:0
(several other counters are supposed to be wrong as well like byteFtdDequeues)

2) Reproducer for unackedMessages:0 for session:
qpid-send -m 11 -a "myQueue;

{create:always}

"
qpid-receive -m 100 -a "myQueue;

{create:always}

" -f

(in another terminal)
qpid-tool
list connection
call <ID_of_qpid-receive-connection> close

and now check result:

grep Tx /tmp/qpidd.log | grep session

should return "unackedMessages:11" but returns zero.
