I did not see such an error for ages, even on the largest sites Nexedi
has implemented, with 300+ users and 10,000,000+documents.
Very long ago (many years), I saw this kind of error in relation with
- Zope sessions
- caching objects into RAM (coding crime)
- misuse of volatile attributes
- creating 2 ERP5 instances on the same Zope (forbidden)

It is not a solution to restart or pack.

I do not see such error on any of our client sites. I suppose that this
error is related to some customisations you made or to the use of
incompatible libraries / versions of python / zope.
