This happens when the process invoked is already over and another request has been sent to for the same process, same conversation to continue.
What you can try is stop the client sending messages to the server, if this is not a production environment, then remove all the aborted processes, and also running processes (from WLI console).
Now restart the client invoking the service/process on the server and check.
