Re: [Zope-dev] Memory Leaks
I do also see the ZPT expression stuff leaking. In my case in this order: Products.PageTemplates.Expressions.SubPathExpr Products.PageTemplates.Expressions.PathExpr Products.PageTemplates.ZRPythonExpr.PythonExpr This one does *not* go away when setting ZOPE_SECURITY_POLICY=PYTHON. I am also leaking refs to persistent User objects; may be a side effect though - like your DateTimes. The site in question serves large ZSQL result sets via ZPT to authenticated users.

Re: [Zope-dev] Memory Leaks
Hmm of course it doesnt mean ZPT expressions are causing the leak, but are a side effect. Of course my DTML ZopeZen is watertight and isnt leaking at all :) - Original Message - From: Stefan H.

No CMF/Plone involved. 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.
