All the sitemap creation tools I've found die at around the 20,000 page mark. Anything out there that does huge sites?
look around http://enarion.net/google/ gent has been around since day one of sitemaps, very accommodating
I found that to not be particularly helpful when most of your site is mod_rewrited. Do you know any others that can go over the 50,000 limit?
you know there is a limit on filesize for google sitemap right? that is why alot of records stop at 50k I wrote a custom one for my site and i was just able to submit 80k urls under the 10mb file limit. Keep in mind my urls are very short in length (mod_rewrited out). I think most sites would be 2x in filesize.
