Hello, We have a rails 2.3 app with a large number of live users, and we have recently done something to corrupt some users sessions in such a way that any attempt to use the session object itself raises an exception. "reset_session" is also raising the same exception, and not clearing the session. Is there a lower-level way to clear the session from the app that doesn't require the session to be valid? We are using the cookie session_store. What is really surprsing to me is that even "cookies['our_cookie_label']=nil" raises the exception. The exception is this: "ActionController::SessionRestoreError (Session contains objects whose class definition isn\'t available. Remember to require the classes for all objects kept in the session. (Original exception: #{const_error.message} [#{const_error.class}])" Unfortunately, since we can't read the session at all, I can't figure out what object is in it that isn't defined.
