Session-scoped form can affect memory footprint on the first load and barely on update. He gets +30M on each load. I doubt that reasonably designed session-scoped form can be at fault here. It would sit there, but it would not grow that fast. There should be something else that he allocates.
BTW, his log shows request-scoped form. Willem, try to create an empty action/form pair and test it. I suppose this is something that you create. Michael.
