Why wouldn't you keep placement-strategy with default
to keep things simple. You aren't using any load-balancing
anyway as far as I understood it.
Haven't used resource-stickiness=INF. No idea which strange
behavior that triggers. Try to have it just higher than what
the other scores might some up to.
I might have overseen something in your scores but otherwise
there is nothing obvious to me.
