I have had this program for years but I ran a forum that automagically generated sitemaps. This one generates about double the urls than that built in one, I use this program about once a year, 167k urls take about 3 hours to run and I also put a 3 second delay on also. That 9000 timeout gave me an error once and then I set it to unlimited and never had another problem. Server stayed at 0.9 to 1.0 server load through the who process but did not lock anything up.
I use this only once and let my daily and new urls be picked up by my forum software.
Everything works perfect, thanks for a great product and thanks for allowing me to update it without paying everytime.
