Scale-in completion never happened: app.js holds the placeholder
Emitter that autoscale-manager returns synchronously (the real
SnsNotifier replaces it later inside an async IIFE), so the completion
poller never saw operationalState change; it also called the
nonexistent scaleIn() rather than completeScaleIn(). Instances in
Terminating:Wait therefore always burned the full lifecycle hook
heartbeat timeout.
In addition, nothing consumed dryUpCalls: a draining SBC kept accepting
new INVITEs sent directly to its public address right up until
termination.
Changes:
- complete the scale-in from within the ScaleIn handler in
autoscale-manager, where the real notifier is in scope
- while draining, reject new INVITEs with 503 so senders fail over to
another SBC (INVITE with Replaces is allowed through since it targets
a call already in progress here)
- a server may run several sbc-inbound and sbc-outbound processes, and
completing the hook when only this process is idle would terminate
the instance while sibling processes still have calls; each process
now reports its call count to redis (lib/call-count-reporter.js, with
a companion change in sbc-outbound) and the draining process
completes only when the server-wide count is zero on two consecutive
checks, falling back to its own count if no reports are present
