I also have a leaking Zope, i'am also using large ZSQL result sets but no ZPT.
I work with a result set of about 500 rows.
I do a lot of stuff for each row of the result set, e.g. setup new objects in zope.
All my work is done in a own product, if i work the first times with it, i could see
my zope grows up about 500MB....
After that a found out, to do a get_transaction.commit(1) after i have done all my work
for each row and the zope was not growing up with such big steps.
I posted this problem some times ago, but no one could give a answer to this problem.
All zope sites a have where we use ZSQL are growing up...
Hope anyone could solve this.....
