I have 3 different versions of Zope running on my machine. 2.33, 2.41, 2,43. I was working on my site in 2.41 and shut it down and started up 2.33 to export some items. I then shut down 2.33 and fired up 2.41 again and when I logged into the management interface, everything was gone. My site folder, all of my installed products, and the wierdest thing of all, I had to delete the default index_html file in my root folder to get apache to work properly, and it is back! It looks just like I just installed it from the tarball. I checked the 2.43 site and everything in it is gone also. The 2.33 install is still fine.

I have backups, but is this normal behavior??? No, I do not think so.

Do you have Python 2.1.3 installed? If not, do it. Also, upgrade to Zope 2.4.4. Python 2.1.1 and Zope 2.4.x (x <= 3) contain memory usage bugs that can exhibit all kinds of weird behaviour. Though, I did not yet here about something drastic as you report now. Dieter
