> Running millions of messages on network described in DISPATCH-1474. This morning's dispatch
master Debug build, and proton 0.29.0 Debug build.
> While a stream of unsettled multicast messages is flowing, then a separate process connects
to EC1, receives a few messages, and then disconnects.
> Eventually the EC1 edge router seg faults with qdr_link_cleanup_CT receiving a conn=0x9999999999999999.
> This setup ran for hours before failing.
> For this command S_RECV is a softlink in my path for proton simple_receive.
> {{var=1; while true; do S_RECV -a $EC1_normal/multicast/q1 -m $var; var=$((var+1)); done}}
