[Zope] zope hangs

A glitch :( It happens in zope 2.3.3 (python 1.5.2) and zope 2.4.0 (python 2.1.1) under OpenBSD 2.7. After a day or two of normal work zope simply stops responding to HTTP requests. When I telnet to 80 port it connects, but nothing else happens. What to do? How to know where it handgs and why? Is it possible to attach to zope process and see what's going there?.. -- Roman V.
