When re-configuring the netty execution context you must make sure that the used execution context has enough threads for netty, in newer versions of Akka you should also see this warning hinting about that:
WARNING: Failed to get all worker threads ready within 10 second(s). Make sure to specify the executor which has more threads than the requested workerCount. If unsure, use Executors.newCachedThreadPool(). -- Johan Akka Team On Fri, Jun 2, 2017 at 5:15 AM, Yutao <[email protected]> wrote: > > Here is the Exception: > > Exception in thread "main" java.util.concurrent.TimeoutException: Futures > timed out after [10000 milliseconds] > [ERROR] [06/02/2017 11:11:55.295] [main] [Remoting] Remoting error: > [Startup timed out.
