Hi Mark,
I had a problem like this some time back. The menu history was filling
up the session data when someone navigated a lot in a session. As I
didn't need the history in the session, I chopped it out and things
improved.
In AuthController I commented out
# session[:goldberg][:menu_history][session[:goldberg][:path]] =
# session[:goldberg][:menu_item]
This may not be your problem, but I hope this helps anyway.
I recently converted my application to run without Goldberg because of
issues like this and the lack of activity in this group.
