python 1.5.2 memory leak?

[Taz]

i'm not very experienced - so the answer may be obvious...

i'm running python code that "runs forver" like daemons. i see that the
memory allocated to it keeps growing using ktop....

i have  taken care to close all objects like file.close() ...
socket.close() -- using the python essential reference book - so i don't
think i;ve lost anything?

can i force garbage collection?

i;'m using python 1.5.2 on redhat 6.2 and mandrake 7.1
