• omission failures: a service is asked for but never rendered. The client might wait forever or be notified about the failure (termination) of the service. • commission failures: a service initiates unexpected actions, e. g., communication that is unexpected by the receiver. The service might wait forever, causing omission failures for subsequent calls by clients. The receiver might be hindered to do its legitimate actions in time. At a minimum, resources are consumed that are possibly needed by others. • timing failures: a service is not rendered before an imposed deadline. System responses will be (too) late, causing corresponding damages to the real world affected by the system. • Value failures: a service delivers incorrect or tainted results. The client continues computations with these corrupted values, causing a spread of consequential application errors.
