If have one of the following plattforms X86/Linux, AMD64/Linux, PPC32/Linux, PPC64/Linux and X86/Darwin (Mac OS X), have a look at valgrind. http://valgrind.org/ I used of often for searching the memory leaks in c++. It's a great tool to analyse your memory behaviour. Greetings -- http://mail.python.org/mailman/listinfo/python-list

Not with python as far I can remember. But often with C++ executables, as i mentioned it. I you look at http://valgrind.org/info/ there stands: Valgrind has been used on programs written partly or entirely in C, C+ +, Java, Perl, Python, assembly code, Fortran, Ada, and many others. It exists also a extension for python http://blogs.gnome.org/jamesh/2008/03/24/python-valgrind/ , to get rid of the false positiv errors. So it should be worth a try. -- http://mail.python.org/mailman/listinfo/python-list

Maybe this one: http://packages.python.org/Pympler/ Haven't used it myself so far though. I also have good experiences with using the module gc calculating histograms of instance-counts.
