This field gives the number of stalled enqueue lock requests
    for new locks that ultimately resulted in a deadlock. Most
    deadlocks are tried again and resolved by Oracle Rdb without the
    application program ever knowing there was a deadlock. Therefore,
    the number shown in this field does not necessarily reflect the
    number of deadlocks reported to the application program.

    Each deadlock reported in the "rqst deadlocks" field is also
    reported in the "rqsts stalled" field. This is because each
    deadlocked request is also a stalled request.
