I think the namespaces in your config are incorrect, deployment config for
an actor should
be under "akka.actor.deployment" (described in the docs here:
http://doc.akka.io/docs/akka/2.4.1/general/configuration.html#Actor_Deployment_Configuration)
and the dispatcher you refer to from your actor is actually under
akka.actor.function-scheduler-dispatcher
in your sample but you then refer to it only by the last name in the path
"function-scheduler-dispatcher".
I think what you intend would be:
akka.actor.deployment {
/function-scheduler {
dispatcher = function-scheduler-dispatcher
}
}
function-scheduler-dispatcher {
... dispatcher config ...
}
I hope this helps
