Add 10033 to that for reporting spills to disc, otherwise the 10032 will
only show you the final memory used during the last merge, and that could
be very deceptive.

Hi Mike,
That's not enough info for deep detailed analysis. Could you trace your
query with enabled trace events 10046 and 10032 (sort statistics) and
provide raw trace files, please? Or at least RTSM reports. You can also
analyze v$sql_workarea (v$sql_workarea_active)
