Claim 0:
1. A method carried out by a processing unit of a computer for detecting a disappearance of a child processing task from an operating environment of the computer, the operating environment executing a recurring parent processing task (TM), the method comprising the following steps:
at each occurrence of the parent task (TM), recording an execution date of the parent task (TM) into a shared memory (M) of the computer;
triggering an occurrence of the child task (TF) on each occurrence of the parent task (TM), the child task (TF) recording an execution date of the child task (TM) into the shared memory (M);
evaluating a parent duration (DTMi) elapsed between an execution date of a last occurrence (TMi) of the parent task (TM), and an execution date of a penultimate occurrence (TMi−1) of the parent task (TM);
evaluating a child duration (DTFi) elapsed between an execution date of a last occurrence (TFi) of the child task (TF) triggered by the parent task (TM), and an execution date of a penultimate occurrence (TFi−1) of the child task (TF);
comparing the parent duration (DTMi) and the child duration (DTFi); and
determining that the child duration (DTFi) is longer than the parent duration (DTMi) to detect that the child task (TF) has disappeared, and subsequently generating an alarm for executing countermeasures to correct for the disappeared child task.
