I have a multiprocessing application that leaks memory. However, the leak is not in the main process (according to Dowser and top) but in the subprocesses. Is there any way I can use Dowser (or similar tool) on subprocesses to trace the leak? If not, how do it trace it?

UPDATE:I spent lots of time trying to use heapy and gnibbler’s code but I couldn’t locate the leak. I then stopped cherrypy in the main process and started another one (with Dowser) in the subprocess. But after a few minutes CherryPy would stop listening to the port… 🙁 So I’m still looking for a better idea.

    I have hunted down the memory leak (which was in external C library) by using muppy – great tool, I wish I found it sooner! Thanks all for the answers.
