Memory leak in python

[Abhishek S]

Hi,

using python2.2.2

I am seeing that the python application is very slowly
eating up the memory. i need help to indentify it.

It start with 11MB and keeps growing by 1 MB around
every 30mins.

Thats not a lot of leak - have you done that over a longer time
period?

let me know how to approch this. gc.collect - does not collect
anything.

Are there any objects in gc.garbage?

Are you writing objects with __del__ methods? If so then that is your
problem probably.

Have you written any extension modules in C?
