The only thing I can think of (since you didn't indicate what the
differences were between the two boxes) is the first argument you passed to
select(). I'm pretty sure you'll never have 31000 descriptors open and I'm
not even sure if the default fd_set can hold that many, leading to your
stack being trashed.
Other things: you should use snprintf, not sprintf and setting the 100th
byte to null is a waste of time.
