Xenu Alternative for Large Sites

[eLocalusa]

We're launching a new site and we're trying to crawl it to check for any problems.  It's millions of pages and Xenu seems to start encountering errors as the numbers mount past 500,000.  Does anyone know of an alternative, free or paid, that could handle the size better?

WEB CEO and seopowersuite try them if it doesnt work: google webmaster tools but you will have to wait until it crawls your site, and not last thing seomoz crawling it has 10 000 limit minimum but it will be enougth to detect major problems

There's a post in the last 24 hours about Xenu and Screaming Frog, it's worth a read to see if a) screaming frog my work for you and b) if the 64 bit version of Xenu mentioned in the comments can solve any problems.
