    I've also experienced this due to CPU overheating; but it wasn't in
    the afternoon. An early morning cron job doing backups via tar
    and scp over a network caused the CPU (which had a dying fan)
    to overheat and the system shut down as a result, as near as we
    could tell in post-mortem. BIOS was apparently set to allow it
    to restart, and loads during the workday never peaked enough
    to tax the CPU as much as the nightly backup. Something of an
    interesting detective case (for us).
