Hi All, As I was going more deeply through the logs, I've found that stacktrace from time-to-time:
2014-05-05 10:03:52,122 ERROR[mySystem-akka.actor.default-dispatcher-22] [akka://mySystem/user/sharding/DeviceActorCoordinator/singleton/coordinator] OneForOneStrategy - key not found: Actor[akka://mySystem/user/sharding/DeviceActor#-1293443401] java.util.NoSuchElementException: key not found: Actor[akka://mySystem/user/sharding/DeviceActor#-1293443401] at scala.collection.MapLike$class.default(MapLike.scala:228) ~[org.scala-lang.scala-library-2.10.4.jar:na] at scala.collection.AbstractMap.default(Map.scala:58) ~[org.scala-lang.scala-library-2.10.4.jar:na] at scala.collection.MapLike$class.apply(MapLike.scala:141) ~[org.scala-lang.scala-library-2.10.4.jar:na] at scala.collection.AbstractMap.apply(Map.scala:58) ~[org.scala-lang.scala-library-2.10.4.jar:na] at akka.contrib.pattern.ShardCoordinator$Internal$State.updated(ClusterSharding.scala:1108) ~[com.typesafe.akka.akka-contrib_2.10-2.3.2.jar:2.3.2] at akka.contrib.pattern.ShardCoordinator$$anonfun$receiveRecover$1.applyOrElse(ClusterSharding.scala:1218) ~[com.typesafe.akka.akka-contrib_2.10-2.3.2.jar:2.3.2] at scala.runtime.AbstractPartialFunction$mcVL$sp.apply$mcVL$sp(AbstractPartialFunction.scala:33) ~[org.scala-lang.scala-library-2.10.4.jar:na] at scala.runtime.AbstractPartialFunction$mcVL$sp.apply(AbstractPartialFunction.scala:33) ~[org.scala-lang.scala-library-2.10.4.jar:na] at scala.runtime.AbstractPartialFunction$mcVL$sp.apply(AbstractPartialFunction.scala:25) ~[org.scala-lang.scala-library-2.10.4.jar:na] at akka.persistence.Eventsourced$$anonfun$akka$persistence$Eventsourced$$recoveryBehavior$1.applyOrElse(Eventsourced.scala:122) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Recovery$State$$anonfun$processPersistent$1.apply(Recovery.scala:31) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Recovery$State$$anonfun$processPersistent$1.apply(Recovery.scala:31) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Recovery$State$class.withCurrentPersistent(Recovery.scala:42) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Recovery$$anon$1.withCurrentPersistent(Recovery.scala:105) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Recovery$State$class.processPersistent(Recovery.scala:31) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Recovery$$anon$1.processPersistent(Recovery.scala:105) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Recovery$$anon$1.aroundReceive(Recovery.scala:110) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Recovery$class.aroundReceive(Recovery.scala:242) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.contrib.pattern.ShardCoordinator.akka$persistence$Eventsourced$$super$aroundReceive(ClusterSharding.scala:1179) ~[com.typesafe.akka.akka-contrib_2.10-2.3.2.jar:2.3.2] at akka.persistence.Eventsourced$$anon$1.aroundReceive(Eventsourced.scala:33) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.persistence.Eventsourced$class.aroundReceive(Eventsourced.scala:205) ~[com.typesafe.akka.akka-persistence-experimental_2.10-2.3.2.jar:na] at akka.contrib.pattern.ShardCoordinator.aroundReceive(ClusterSharding.scala:1179) ~[com.typesafe.akka.akka-contrib_2.10-2.3.2.jar:2.3.2] at akka.actor.ActorCell.receiveMessage(ActorCell.scala:516) [com.typesafe.akka.akka-actor_2.10-2.3.2.jar:na] at akka.actor.ActorCell.invoke(ActorCell.scala:487) [com.typesafe.akka.akka-actor_2.10-2.3.2.jar:na] at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:238) [com.typesafe.akka.akka-actor_2.10-2.3.2.jar:na] at akka.dispatch.Mailbox.run(Mailbox.scala:220) [com.typesafe.akka.akka-actor_2.10-2.3.2.jar:na] at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(AbstractDispatcher.scala:393) [com.typesafe.akka.akka-actor_2.10-2.3.2.jar:na] at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) [org.scala-lang.scala-library-2.10.4.jar:na] at scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) [org.scala-lang.scala-library-2.10.4.jar:na] at scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) [org.scala-lang.scala-library-2.10.4.jar:na] at scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) [org.scala-lang.scala-library-2.10.4.jar:na] I've got similar exceptions for all the actors that I use with the cluster sharding. Any idea if this could be linked with the fact that I can't restart my application? Also, any idea why I'm getting such an exception?
