Hello everybody, after much gnashing of teeth and pulling out of hair we finally seem to have found the error in our ways. What we were doing led to a massive memory leak and I thought I'd let everbody know so you know what to avoid. Our setup is something like <dtml-document or method> calls <pythonscript> and <pythonscript> calls <restrictedTraverse> for some given <path>. The resulting <object> is then used to render some content and the resulting data is returned. Here comes the warning: If you don't explicitly set the <object> obtained by <restrictedTraverse> to <None> (maybe you could <del> it instead just as well) this <object> will be leaked with any <subobjects> instantiated along the way, namely a <ImplicitAcquirerWrapper> and (in our case) a <DateTime>. Hope this helps someone somewhere.
