Hi.
With akka http 1.0-RC2 (was similar in 1.0-RC1), one of my program signals
an intermittent error that I do not understand.
The context: one HTTP GET request is sent out, the JSON response is
properly received, decoded and acted upon, and then the system terminates
with (system being my ActorSystem):
Await.ready(Http().shutdownAllConnectionPools(), 5.seconds)
system.shutdown()
The error only happens from time to time (I’d say once every three runs). I
have activated akka.actor.debug.{receive,autoreceive,lifecycle,fsm}.
Any idea of what could be the cause?
