    It is not recommended to increase __FD_SET's size. Unfortunately,
    however large you make it, libc simply cannot cope with a select size
    larger than 256 fd's.

    As for the other parameters, you don't need to recompile the kernel.
    In all post-1.3.57 kernels, you could achieve your inode and file
    limits by (as root):
    echo 4096 > /proc/sys/kernel/inode-max
    echo 2048 > /proc/sys/kernel/file-max
