Thanks, 

That explains a problem I had deleteing around 33,000 rows.  I let
it run for a couple of hours and it did not work.  I finaly had to
select all the primary keys of the rows I wanted to delete and 
delete the rows one at a time, it was doing about 120 rows/min.

Is this fixed in 7.2 ?

Thanks again

marc
