Error when scheduling akka system with quartz scheduler

[Amruta]

I have scheduled a task that the actors carry out at a scheduled time(every 5 minutes). When I deploy my app the first time it runs fine but on the second and consequent runs it gives the folllowing error 

09:22:00.006 [schedulerFactoryBean_Worker-2] ERROR (:) - Job DEFAULT.jobDetailFactoryBean threw an unhandled Exception:

I have used reaper  concept for shutdown strategy and I terminate the system after all children actors are done working.

Do I need to refresh/reload the actorSystem in some way?

[Amruta]

So now I am not killing the actorSystem since my scheduler wont load the config on every run. But then I get a new error

akka.actor.InvalidActorNameException: actor name [actor-name] is not unique!

In the previous run i kill the actor after work is done so i expect it to not throw this exception.
