Hi !
I'm currently working on making an existing app a universal binary. I have noticed that my select() code that worked fine in ppc stops working when running on intel when I have more than 1024 active file descriptors (I'm accessing disk files (sometime LOTS of them) and tcpip sockets).


Sounds like you should read up on FD_SETSIZE in man select:

The behavior of these macros is undefined if a descriptor value is less than zero or greater than or equal to FD_SETSIZE
