[Zope] memory leak?

I'm Running Zope 2.7.0 and python 2.3.3 on Debian with kernel 2.6.4 I'm experiencing a rather anoying memory leak (?) wich causes the need of a restart of zope once a week or so. something in my zope causes the swap-partition to fill up (1,5 Gig), and eventually zope will stop responding. When I restart zope, Everything is back to normal, and the the swap partition slowly starts growing again. I have a sneaking suspicion that this is caused by some External methods (we are using a lot) So: How may I track memory usage in zope, particulary: How can I find out wich object is "gun on the run".
