Renato, Out of curiosity, how long are your TGT sessions for? In order to facilitate single sign out, each ticket now keeps a map of services that it was registered for so that it can log the user out. If your users are accessing a large number of applications per session this could get rather large. Do you know the average number of applications per TGT session?
