Comment (by whocares):
The problem could be that you simply didn't wait long enough.
In your configuration, Varnish would at least need 15 seconds (3 good
replies with a wait time of 5 seconds between each try) before actually
processing client requests. In the meantime it will reply with 503
"Service Unavailable" because that's exactly what Varnish thinks is the
case.
As soon as you disable one of the .probe configs, Varnish will see the
node with the probes disabled as immediately available and start serving
requests from there until the second backend is successfully checked and
also used in the loadbalancing setup. That's why it works for you when
just checking one backend system.
