Jo, Really? Wow, you'd think such a required behavior would be documented ... Unless I missed it somewhere. I do indeed use quite a bit of Python Scripts ... Problem is many of them are part of the CMF ... I really don't want to have to go through every bit of python script I have to do this, and would much prefer finding the root cause! Maybe I'll go digging for documented bugs and possible patches concerning Ptyhon Scripts ...

Well, I'm still not having any luck tracking this down ... I've tried to keep a nice and close eye on the top refcounts, but I'm not seeing anything strange, the really big delta is on the DateTime object, as the refcount seems to vary quite a bit, but the top one is fairly stable.

Do you use PythonScripts (ZODB-based that is, not Products)? We had the same effect as the one you describe and solved it at least partially by setting every object used inside our PythonScripts to None before returning from the script. So if you have code along the lines of "something=context.restrictedTraverse('whatever')" or "baz=foo.objectValues(bar)" (or anything like that) try setting "something=baz=None" before the script ends. BTW: LeakFinder is a great tool, very useful in my experience and I deeply regret that it is no longer working with 2.6. Be prepared to restart your Zope after using it though.
