Recently I had the same issue.
akka.remote.netty.tcp.port was set to 0 but actor system was trying to bind
on 2552.
The problem was that actor system was lazy val in my specs but config it
was using wasnt, like following:
trait CommonSpec extends TestKitBase {
val config: Config = mkConfig
implicit lazy val system: ActorSystem = ActorSystem("api", config)
}
This mistake made system initialize twice: with the default config values
(config val at the system initialization moment was null) and again with
right config value.
