CKAN version 2.8.4
ckanext-pages commit 06d8ef5

Each single request to our CKAN instance causes lots of entries in the error log. The exception is caused when creating the navigation bar:

The version is from 2018, but the responsible code hasn't been changed, as far as I can see.

We've been seeing this too, there might be some race condition somewhere in the database initialization as usually this is fixed for us by restarting everything.
