> When implementing https://github.com/apache/qpid-dispatch/pull/111 I stumbled across an issue with an autoLink or linkRoute only being able to refer to more than 1 connection, which I assumed would originaly cause an assert in route_control.c:350 to trigger when I configured an autoLink to trigger on a containerId and use the same container id when sharding a queue.
> Since the assert didn't trigger, I assumed that I must have misread the code, but nontheless as part of the patch I made it possible for a linkRoute/autoLink to be associated with multiple connections.
> Recently, I have seen some router crashes when scaling up and down queues in EnMasse, and I just figured that the reason for this assert not triggering is that it is disabled in the RelWithDebInfo configuration.
> If built without optimizations (Debug), I'm able to trigger the issue with the configuration in http://people.redhat.com/~ulilleen/bugs/routerconn/
> To trigger, I startup the router and broker as so:
> qdrouterd -c router_incoming.conf
> export MESSAGING_SERVICE_HOST=localhost
> export MESSAGING_SERVICE_PORT_INTERNAL=55673
> export QUEUE_NAME=myqueue
> export CONTAINER_ID=myqueue
> ./br/bin/simplebroker &
> ./br/bin/simplebroker
> I have extracted the patch from DISPATCH-476 and will create a PR with it.
