[Zope] memory leaks in Zope application

[John Doe]

Hi,

I'm running a Zope-application (2.5.1, Python 2.1.3)
on a dual processor (1 GB mem) Redhat 7.3 machine.
User-authentication is done by the
exUserFolder-product (on Postgresql 7.2.1). An
apache-server runs in front of the Zope server. RAM
Cache Managers are used, number_of_threads in z2.py is
set to 20. 

Performance is excellent, but every 2-3 days Zope
crashes. Reason: Zope start with allocating 140 MB of
RAM and steadily (over 2-3 days) increases memory
usage to 1   GB. At this point it crashes. 

Has anyone encountered this problem?
ronny.
