In one customer site I see zillions of messages like this one on the event log:

2017-11-17T10:39:56 ERROR ZODB.Connection Couldn't load state for 0x130e

I have never used plone.openid and I don't see it in the instance eggs; I don't know if the customer installed it and then somehow removed it.

have anybody seen this before?

any hints will be appreciated.

this is Python 2.7.6 and Plone 4.3.11.

The quick way is to provide an alias, see e.g.:

https://github.com/plone/plone.app.upgrade/blob/master/plone/app/upgrade/init.py#L70

Then probably you can even find where that persisntent broken object is and remove it.

thanks! I think I'm going to include plone.openid on the buildout to see what happens.

I'm guessing that your installation used to depend on the Plone egg (which has as dependency on openid) and currently just on Products.CMFPlone (which doesnt').

Just add the egg to the instance:
http://dist.plone.org/release/4.3.11/versions.cfg
plone.openid = 2.0.4
plone.app.openid = 2.0.4
