I'm not an expert at linux kernel internals, but AFAIK even if the 
server is leaking, the kernel should reclaim the space when the process 
is stopped.
You wrote you use kernel 2.4.0, that's very brave I'd say. I know it's 
easier said than done, but you better first install an newer linux 
kernel before looking at the zope stuff. You get at least the promise of 
a saner out-of-memory behavior.
Other things you can do are setting process limits, so that the ZEO/zope 
servers cannot bring down the whole machine.
There's also a zope specific product from chrism, autolance (search 
zope.org) which makes zope monitoring and restarting itself, when some 
conditions (memory etc.) are met.
