Because you might have kept references somewhere. And nobody knows where without you showing code. Lots of long-running memory intensive apps such as ZODB are written in python - so I doubt that it is a problem of python itself, but instead of your program. Try and reproduce the behavior with a self-contained script - if that still exposes the problem we can look at it maybe fixpython if needed. Besides: _if_ it was a python error, you'd have to move to a knew python version anyway, won't you? And just because you McMillan Installer won't work doesn't mean that YOU can't try python2.4 or even 2.5, and see if it works better. Diez -- http://mail.python.org/mailman/listinfo/python-list
