Same things does ocassionally (few weeks nothing, then every 2-3 days etc)
for me with Zope 2.5.1, W2k TSE. I was moved to Linux Mandrake 9.1, runs
without restarting for 1/2 year!

Our NT admin says me after deep researching that this error is probably in
NT and not in Zope but does not know exactly which DLL or so it is. Yes, I
was have installed Plone too, but not used. Memory consumes at first look
Zope, but in detailed look thins memory consume some component from NT.

In finally, my Zope runs now 2-10 times (100 for images) faster than on NT
on slower HW and I cannot overload it (I was overload local mirroring
machine and not Zope).

Try Linux, it is easy to do with Mandrake.
