In 2.4.0 there is a new utility to remove the internal cluster sharding data http://doc.akka.io/docs/akka/2.4.0/scala/cluster-sharding.html#Removal_of_Internal_Cluster_Sharding_Data .
The most common reason for problem a is using auto-down and I highly recommend that you use the Typesafe Split Brain Resolver <http://doc.akka.io/docs/akka/rp-15v09p01/scala/split-brain-resolver.html> or some similar downing strategy.
