Most likely you keep references to objects you don't need, so python
garbage collector cannot remove those objects. If you cannot figure it
out looking at the source code, you can gather some statistics to help
you, for example use module gc to iterate over all objects in your
program (gc.get_objects()) and find out objects of which type are
growing with each iteration.
