I'm not sure of the exact cause of this error, but I'll note that one your deployment looks like it's using the "slow" (non-C) versions of the stuff in zope.interface, which usually means that somehow the zope.interface C extensions couldn't be compiled. You might try checking this from a debug prompt:
It should look like this: >>> from zope.interface import implementedBy >>> implementedBy <built-in function implementedBy> You're not using the C extensions if it looks something like this instead: >>> from zope.interface import implementedBy >>> implementedBy <function implementedBy at 0x51cf70> I'd start by getting that fixed if possible. - C On 6/15/09 9:33 AM, Jose Benito Gonzalez Lopez wrote: > Dear ZODB developers, > > We are experiencing some errors and we'd appreciate any idea or advise. > > Our web application (http://indicodemo.cern.ch) uses ZODB: > - ZODB 3.4 in production > - and ZODB 3.8.0 for testing. > Both versions work smoothly. > > Now, we are moving to ZODB3 3.8.1 (in a fresh installation of the web > appl.).
