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.

    The number reported in the "rqsts stalled" field is also included
    in this number.
