 Sorry guys, quick update:

 Time interval actually affects the situation: if actor job time <
 scheduler interval, everything is good, no matter how many actors we have.

 When actor job time > scheduler interval and ACTOR_COUNT < 30,
 envelopes filling up and not garbage collected (millions of them after a
 few hours).
 *But if I increase ACTOR_COUNT up to 30, GC starts to delete those
 not-delivered messages, according to the profiler.*

 Why? Looks like something in Akka starts working differently after that
 magic threshold.

 Any ideas?

Yes, it is. Now it's clear. Thank you.

That problem does not happen in Akka Streams, it explicitly manages
flow-control by the way.

Of course it builds up if you can't process the messages equal-or-faster
than you get them?

My guess is that your default dispatcher has ~30 threads

Sorry guys, quick update:

Time interval actually affects the situation: if actor job time < scheduler 
interval, everything is good, no matter how many actors we have.

When actor job time > scheduler interval and ACTOR_COUNT < 30, envelopes 
filling up and not garbage collected (millions of them after a few hours).
*But if I increase ACTOR_COUNT up to 30, GC starts to delete those 
not-delivered messages, according to the profiler.*

Why? Looks like something in Akka starts working differently after that 
magic threshold.
