In November 2008 I observed that the scanner didn't do the "large file check" that it 
is supposed to do for files > 2GB, when it scanned the University of Muenster mirror.

(Reported in the openSUSE bug tracker at the time, and now moved here.

I supposed that something is special about that mirror that prevents the check from 
happening; for all other mirors it seemed to work.
