FD_SETSIZE and apache

[rainer at ultra-secure.de]

Hi,

I am starting to get the the old
[Thu May 12 12:26:24 2011] [error] [client ip.ip.ip.ip] (20)Not a
directory: FastCGI: failed to connect to server
"/home/user/cgi-bin/php5-fcgi.fcgi": socket file descriptor (1090) is
larger than FD_SETSIZE (1024), you probably need to rebuild Apache with a
larger FD_SETSIZE


error again.
I've got
FD_SETSIZE=16384U in make.conf
and I even changed the source in
/usr/include/sys/select.h

But I still get these errors.

This is FreeBSD 8.2 amd64.

Does anybody have an idea what I'm doing wrong?
