Brief: unable to scale an app up to web=2 or greater. Tried both node and rails app.
Through docker listing and log tailing I see in both cases that app container successfully starts, but fleetctl shows the unit as:

UNIT                        DSTATE      TMACHINE        STATE       MACHINE         ACTIVE
qpb-dev_v6.web.2.service        launched    8106c0f9.../10.21.1.120 inactive    -           -

web=1 -> web=0 - works
web=0 -> web=1 - works
web=1 -> web=n, where n>1 - doesn't work
