Error occurs when sending large message.

[jiyeongj]

Hello.

I'm using Akka.Remote 1.3.12, Akka 1.3.12 on .NET Framework 4.6.1.

Test Scenario

This is Issue case.

1. TestMainActor sends to TestSubActor using ActorSelection.

2. If, TestSubActor is busy, Error occurs Akka.Actor.ActorNotFoundException.
   Error occurs when sending large message. (The size of the test message is about 63 MB.)

Test Result

I'm really sorry I never replied to this, particularly since we have a blog post that describes why this issue happens - this is happening over Akka.Remote, correct?
