If you are using Conditional Trace or System Insight, creates Image Added creates Akka cluster clients on the relevant ECs. In the case of 'catastrophic communication failure' between the client and the Akka cluster, the EC client will quarantine the SC cluster. If this occurs, you must restart the entire SC cluster according to the relevant example scenario described below. For further information, see Lifecycle and Failure Recovery Model in https://doc.akka.io/docs/akka/2.4.12/scala/remoting.html.

For further information on the mzsh akka command, see 2.2.1 akka in the Command Line Tool user's guide.
