Hi, I am moving a site from my server (linux, python 2.1.3, zope 2.6.1) to hoster's machine (FreeBSD 4.x, Python 2.2.2, Zope 2.6.1 (2.6.2 tested too)) Site is accessed through Apache using mod_rewrite and VHM (at port 80) and also directly at port 8082. When i access some pages at mysite.com:80, i get === ERROR(200) zdaemon Process xxx terminated by signal SIGSERV(11) (core dumped) === and server restarts. In the browser i get Proxy Error: zero-sized reply. It never happens when i access mysite:8082. Sometimes i can access mysite:80 if i open and re-save one or another zpt through ZMI (mysite:8082) - the site remains accesible for several minutes until it dumps core again. And i noticed that some pages of the site doesn't cause server restart, and other pages did it very often. My site uses following products: PageTemplates, PythonScripts, OrderedFolder, TextIndexNG and Epoz. No CMF or Plone or whatever. There are zope/var/python.core file, but i am unfamiliar with gdb and can't get any useful info with it What is the possible causes of this segfaults? What can i do to narrow the problem? Thanks
