Question

This happens only for some users when signing in (heroku production) From the logs:

    Started POST "/users/sign_in?locale=en"

     RuntimeError (Devise trackable could not save #<User id:

    cache: [POST /users/sign_in?locale=en] invalidate, pass

The 5 devise Trackable database columns are on the user model and have valid looking values for this user. User cannot log in

This is happening since upgrading to devise 2.2.3 from 1.x
