The first event sets the id of the actor to 1. The second and third events are sent to the successor of the actor with id 1. The successor of the actor with id 1 is the actor with id 2. The successor of the actor with id 2 is the actor with id 3. The successor of the actor with id 3 is the actor with id 1. The bug is that the actor with id 2 is not notified of the second event, NotifySuccessor(2). The bug is found by Coyote after 100 iterations of the testing
