Pavel Moravec updated QPID-6213:
--------------------------------
    Attachment: qpidd.log.gz

I tested current upstream with Chuck's patch, but.. I still see the same 
problem as before (maybe little more often than without this patch).

Attached are trace logs from the broker.

Reproducer:

./src/qpidd --auth=no --max-connections=10000 --queue-purge-interval=60 
--log-to-file=/tmp/qpidd.log --trace --log-to-stderr=no

Then run bash script:
noDelQueues=1000

if [ $# -gt 0 ]; then
        noDelQueues=$1
fi

maxIter=180
mySleep=10

echo "$(date): creating $noDelQueues connections.."
for i in $(seq 1 $noDelQueues); do qpid-receive --connection-options 
"{'heartbeat':5}" -a "autoDelQueueNoBound_${i}; {create:always, node:{ 
x-declare:{auto-delete:True, arguments:{'qpid.auto_delete_timeout':1}}}}" -f 
--print-content=no > /dev/null 2>&1 & sleep 0.1; done

iter=0
while true; do
        iter=$(($((iter))+1))
        conns=$(pgrep qpid-receive | wc -w)
        echo "$(date): iteration:$iter connections:$conns"
        if [ $conns -lt $noDelQueues ]; then
                echo "error: found just $conns connections instead of 
$noDelQueues, in iteration $iter"
                break
        fi
        if [ $iter -eq $maxIter ]; then
                echo "no error"
                break
        fi
        sleep $mySleep
done

that usually finishes in 5-15th iteration (by error).

> Caused by https://issues.apache.org/jira/browse/QPID-5758. Reproducer from 
> Pavel Moravec: create many heartbeat enabled connections and queues (e.g. 500 
> idle receivers, each with their own queue) and have the purge interval 
> relatively short (to speed up reproducing).
> The broker misses heartbeats and connections get timed out.
