Hi, Now that I did this (ulimit -a) thing, I have a new problem... when I am trying to select on more than 1200 file descriptors (in the select system call), I get a bad filedescriptor error... but when I do a fstat on each filedescriptor I sent into select (using FD_SET), I dont see that any filedescriptor is bad... and from there, select just gets wegded... What am I doing wrong?
