It's typically caused by multiple persistent actors with the same persistenceId running at the same time. E.g. because there were a network split and your cluster was split into two separate clusters and thereby starting multiple persistent actors. That is why we so strongly recommend against using auto-downing and instead recommend Split Brain Resolver <http://doc.akka.io/docs/akka/rp-current/scala/split-brain-resolver.html> or similar.
Now you need to cleanup the corrupted data before starting the system. http://doc.akka.io/docs/akka/2.4/scala/cluster-sharding.html#Removal_of_Internal_Cluster_Sharding_Data Have you changed the default mode=repair-by-discard-old in the config of the replay filter? https://github.com/akka/akka/blob/master/akka-persistence/src/main/resources/reference.conf#L131 Regards, Patrik On Tue, Aug 2, 2016 at 9:44 PM, Eric Swenson <e...@swenson.org> wrote: > I'm getting this error consistently now, and don't know why this is > happening nor what to do about it.
