If the directive is set to ``{16.Gb*task.attempt}``, the memory used will be 16 Gb multiplied by the number of attempts. By default LMAS is set to run a maximum of 2 retires per process. If the maximum resources are reached before the maximum number of tries, these won't be incremented beyond the defined limit.
