[Zope-dev] Zope unresponsive

Hello, My zope server has become unresponsive: when I attempt to start it all I can see in top is a python process fluctuating between 0 and ~30MB in res RAM using 30% CPU. When I try zopectl debug I get the following message after which zopectl exits: python2.3: Modules/ gcmodule.c:231: visit_decref: Assertion `gc->gc.gc_refs != 0' failed. I'm running Linux Fedora Core 3, Python 2.3.4-11, Zope 2.7.4-1 Thank you, Aleksandr
