I have it running for more than 1 hour... the main application
software runs for about 50 days non stops and the memory just keep
I have a pdu.py class which has about 130 methods that's been created
on the fly. If you substitute the above code of PDU() init with the
pdu class from pdu.py, I see a dramatic increase in RAM in python
2.4.4! But not in version 2.5.1. So I upgraded to the latest
version... I still see the main application uses more and more memory
as the time goes by...
What should I do next? Can I force garbage collection manually? If so,
how do I do that?
