> -----------------------------------------------------------------------------------------------------
>
> Key: PROTON-2344
> URL: https://issues.apache.org/jira/browse/PROTON-2344
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.33.0
> Reporter: Pavel Moravec
> Priority: Major
> Attachments: mimic_goferd_consumer-with-receive-noSSL.py
>
>
> Packages used from EPEL:
> * qpid-proton-c-0.33.0-1.el7.x86_64
> * python2-qpid-proton-0.33.0-1.el7.x86_64
>
> reproducer idea: connect to a broker with a consumer and some heartbeat set, and mimic dropping packets until the client drops the connection.
>
> Particular reproducer:
> * create a queue pulp.agent.TEST.0 in a broker
> * run below reproducer script (can be further simplified, just modify the ROUTER_ADDRESS)
> * mimic packets drops on output:
>
> {noformat}
> port=5647
> a="-I"
> while true; do
> echo "$(date): setting $a"
> iptables $a OUTPUT -p tcp --dport $port -j DROP
> if [ $a = "-I" ]; then
> a="-D"
> else
> a="-I"
> fi
> sleep 5
> done{noformat}
>
> .. and monitor memory usage and CLOSE_WAIT connections.
>
> The issue sounds to be a regression from python-qpid-proton-0.28.0-3 where I cant reproduce it.
