In contrast, a process suffering a total failure can be quickly identified, restarted, or repaired by existing mechanisms, thus limiting the failure impact. 71% of failures are triggered by a specific environment condition, input, or faults in other processes. In 13% of cases a module became a zombie with undefined failure semantics.
