    if at least one incident is not in the incident receive queue;

    determining whether the last incident completed checkpoint matches a last incident analysis pool selection checkpoint;

    if the last incident completed checkpoint matches the last incident analysis pool selection checkpoint, selecting as the restart incident checkpoint, a monitor checkpoint; and
