Hi
I have a strange problem when reuse an actor, (the error is random!)
This is my scenario:
- send 40 async request (messages) to my principal actor.
- principal actor send every single request (message) to 10 secondary
actors.
- secondary actors reply to an assembler actor who collect the results and
send the final result.
I resuse every time same actor in this way:
private ActorRef getActor(String actorName) {
Option<ActorRef> child = getContext().child(actorName);
if(child.isDefined())
return child.get();
else
return
getContext().actorOf(SpringExtProvider.get(getContext().system()).props(actorName).withRouter(new
SmallestMailboxRouter(4)), actorName);
}
(this is "like" store actors in map or cache, its correct?!)
and this is the error that return to me in random way at execution time:
[ERROR] [02/03/2014 18:40:19.248]
[OrchestrationApplication-akka.actor.default-dispatcher-2]
[akka.dispatch.Dispatcher] actor name [actorName1] is not unique!
* akka.actor.InvalidActorNameException*: actor name [actorName1] is not
unique!
at
akka.actor.dungeon.ChildrenContainer$NormalChildrenContainer.reserve(ChildrenContainer.scala:130)
...
[ERROR] [02/03/2014 18:40:19.248]
[OrchestrationApplication-akka.actor.default-dispatcher-2]

* akka.actor.InvalidActorNameException*: actor name [actorName2] is not
unique!
at
akka.actor.dungeon.ChildrenContainer$NormalChildrenContainer.reserve(ChildrenContainer.scala:130)
...
etc etc...
why this error? if the actor is defines (also actor name) why system try
to recreate actor?
I think that if an actor dead or is stopped also his name is removed of
actopr system, or not?
ps:
my dispatcher is default dispatcher, and I have a 4 core processor (i5)
teh default config for dispatcher is:
fork-join-executor {
parallelism-min = 8
parallelism-factor = 3.0
parallelism-max = 64
}
throughput = 10
its correct?
tnx!
