Thanks. The "magic number" appears to be 639 - I can schedule 639 at a time but not 640.

When I schedule 600 or fewer bouts at a time, the autoscheduler works fine.

However, when I schedule 640 or more, and then try to fight them, it gets through all of the fights, but then crashes.

The only restrictions I have are "men only" and "ratings within 25 of each other".
