FD_SETSIZE only controls how big the fd_set used by select() can be; there are other limits. For info about the limits on file descriptors and how to raise them, see http://www.kegel.com/c10k.html Depending on what kernel and what program, it might be as easy as echo 32768 > /proc/sys/fs/file-max echo 65536 > /proc/sys/fs/inode-max and then, for the process in question, ulimit -n 32768 - Dan
