Error while connectiong to journal and subsequent system termination

[patrykks]

When trying to run the application with current configuration (either through activator or simply using SBT) I get following error:

[ERROR] [05/08/2017 16:27:34.379] [ClusterSystem-akka.actor.default-dispatcher-15] [akka.actor.ActorSystemImpl(ClusterSystem)] Lookup of shared journal at akka.tcp://ClusterSystem@127.0.0.1:2551/user/store timed out

which causes the immediate system termination.

I think, I solved the puzzle. The problem was to short sleep after starting the first Backend. Probably there were too many messages send to journal and it cannot send reply for Backend2. Probably this is why we get dead-letter for Identify message. Interestingly, while observing almost 100% failure for 5sec delay, increasing the interval by just 1s I get 100% success.

Hi @patrykks, thanks for the feedback! Seems nice to fix that in the example, could you create a PR?
