Hi,
i think you must keep in mind that tdom persistent objects are just available in the thread in that they were created. If the different install tcl files are served by different threads, the relevant tdom objects will not be available. The best way to go is to delete every doc at the end of one page and recreate it in the next tcl page from the underlying xml doc. Otherwise you have tdom objects lying around that you maybe cannot use in the "next" page and that just need memory.
