Hello, all. Quick background info: Developing on Linux box (2.2.x kernel) w/ Python 1.5.2 + Zope 2.2.2. (Call it "DevBox") The Powers That Be have said actual "production" platform is Linux 2.4.1 kernel, Python 2.0, Zope 2.2.2. (Call it "ProdBox"). So I: 1. Stop Zope on both boxes. 2. Move $/Zope/var/Data.fs* and $/Zope/Extensions/* from DevBox to ProdBox, untar/gunzip Products on ProdBox. 3. Verify/adjust permissions as necessary. 4. Start Zope on ProdBox (running as user "zope", not root). ProdBox runs (seemingly) okay w/ stuff from DevBox, except... A. Zope start up errors: WARNING: Python C API version mismatch for module cStringIO: This Python has API version 1009, module cStringIO has version 1007. (This module plus a list of 25 other modules.) They don't keep Zope from running, but I wonder if this is the root of my other problems(?). Anyone know of incompatibility issues b/w Zope 2.2.2 and Python 2.0? B. Also, user logins kill Zope, but it restarts on its own. Example: Went to http://ProdBox. Cool. Went to http://ProdBox/Folder. Cool. Went to http://ProdBox/Folder/DTMLMethod. (User login required) username: ***** password: ***** "Server not responding, using cached copy" error (wtf?). In my telnet window, I see text scrolling because Zope just started (restarted). Click click click, all is seemingly well now... Went to http://ProdBox/manage (Zope management interface, different user login required) username: ***** password: ***** "Server not responding, using cached copy" error (wtff?). In my telnet window, I see text scrolling because Zope just started (restarted) yet again. Anyone have any idea why Zope is dying and instantly starting up again (as far as I can tell it only happens @ login)? Could this be related to the Z2.2.2/P2.0 incompatibility issue (if any)? I'm wary of upgrading to Zope 2.3.0 based on problems I had last time I upgraded (lots of stuff 'broke' in the transition), but not 100% adverse to the prospect of doing so. Any ideas, suggestions, fixes, zen, or anything like that? Any/all help is greatly appreciated. Thanks. -Gary
