I would recommend you to run ./configure with --with-maxfd=you_desired_limit and --enable-epoll Watch for messages like this in configure output: checking if epoll works... yes Using epoll for the IO loop. ... Maximum filedescriptors set to 131072 ... Having large number of FDs with select is dangerous. Also, I recall there was an issue on increasing FD_SETSIZE on glibc (Linux uses glibc).
