* Log a warning if 'akka.remote.log-frame-size-exceeding' contains a bad value Currently, if 'akka.remote.log-frame-size-exceeding' is accidentally set to an invalid value (e.g. 'on') the developer does not get warned but remote communication fails with a not-very-helpful error message: ``` [INFO] [06/29/2018 15:07:41.657] [run-main-0] [akka.remote.Remoting] Starting remoting [INFO] [06/29/2018 15:07:41.847] [run-main-0] [akka.remote.Remoting] Remoting started; listening on addresses :[akka.tcp://akkaremotenull@localhost:2553] [INFO] [06/29/2018 15:07:41.849] [run-main-0] [akka.remote.Remoting] Remoting now listens on addresses: [akka.tcp://akkaremotenull@localhost:2553] [WARN] [06/29/2018 15:07:41.986] [akkaremotenull-akka.remote.default-remote-dispatcher-5] [akka.tcp://akkaremotenull@localhost:2553/system/endpointManager/reliableEndpointWriter-akka.tcp%3A%2F%2Fakkaremotenull%40localhost%3A2552-0] Association with remote system [akka.tcp://akkaremotenull@localhost:2552] has failed, address is now gated for [5000] ms.

Akka 
We believe that writing correct concurrent & distributed, resilient and elastic applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction.
Akka is here to change that.
Using the Actor Model we raise the abstraction level and provide a better platform to build correct concurrent and scalable applications. This model is a perfect match for the principles laid out in the Reactive Manifesto.
For resilience, we adopt the "Let it crash" model which the telecom industry has used with great success to build applications that self-heal and systems that never stop.
Actors also provide the abstraction for transparent distribution and the basis for truly scalable and fault-tolerant applications.
