Hi there,
I'm trying to debug a ConnectionStateError that my pyramid_zodb app
occasionally shows. I could not find any condition that causes the
error so it looks like it is occuring randomly. The only thing that is
common to all occurences is that the error happens during
authentication.
Is it possible the database connection from the app to the ZODB is
closed when the authentication happens?
Many thanks for your help in adavance,
Sascha
