Hello, I've just tried and failed to upgrade to 2.2.4 from 2.2.2. A python instance starts up and slowly swallows the CPU, ending with 99% of the CPU. A second python instance starts and doesn't do anything naughty. If I issue a ./stop, the second python instance ends properly, but the first continues to consume all CPU resources. I've tried recompiling it several times, reinstalling Python, but no go. It did once start up properly, but as soon as I tried logging into Zope, python took over the CPU. I'm using OpenBSD 2.8, python 1.5.2, x86, 196MB of RAM, GBs of free disk space. I've been using Zope since 2.0 and have never had this much trouble upgrading. the only Zope product I'm using is SiteAccess (the same setup as the old Zope.org before the cluster upgrade). Any ideas? thanks, Luke
