Mechanisms for managing task events during the scheduling period of a task executing on a processor. Only events of specific portions of the scheduling period are logged, wherein a first shared resource access has been granted for the task, this portion of the scheduling period involving gathering all the non-deterministic events which cannot be replayed by simple task re-execution. Other independent non-deterministic event records are still logged as usual when they occur out of the portion of the scheduling period for which a record has been created. This limits the number of logged events during a recording session of an application and limits the frequency of events to transmit from the production machine to the replay machine.
