Hello once more,

I’m running a fresh Zope2 ZEO setup (pip install --index-url=http://download.zope.org/Zope2/index/2.13.22/ Zope2 and pip install zope.mkzeoinstance) inside a virtualenv setup.

As said: No products, fresh setup, happens with any object. Going to any undo tab produces this error: Error Type: DisconnectedError

Client log:

The path difference in /opt/python/2.7.9/lib/python2.7/asyncore.py vs /opt/python/zope2-latest/lib/python2.7/site-packages make me wonder if this is a bug or a problem with my setup?

Client + ZEO server were created from the same virtualenv.

Python 2.7.9 build from source.

Any ideas?

Best, Sebastian
