I want to use Akka Remoting to exchange message over network between actors, but for large String message i got the following error: akka.remote.OversizedPayloadException: Discarding oversized payload sent to Actor :: max allowed size 128000 bytes , actual size of encoded class scala. How can i fix this limitation? I add the following configuration and now everything is ok: akka { actor { provider = "akka.remote.RemoteActorRefProvider" } remote { maximum-payload-bytes = 30000000 bytes netty.tcp { hostname = "127.0.0.1" port = 2552 message-frame-size = 30000000b send-buffer-size = 30000000b
