Have you checked the permissions? I seem to remember i had the same
problem once with lighttpd and it was because permissions of the
socket under /tmp. Now my server works OK since ages. I had to
take provisions for permissions in the fastcgi python responder. In my case
the relevant bits are when daemonizing the responder:
pid = os.fork()
if pid > 0 :                    # In first child
    import time
    time.sleep(3)
    while not os.access(socket, os.F_OK) :
        time.sleep(1)
    # the socket created by the child is made accessible to the web
    # server
    os.chown(socket, wwwuid, wwwgid)
    os.chmod(socket, 0700)
    sys.exit(0)                 # Exit first child
....

While still being root i adjust the permissions of the socket. Then 
i change effective userid:

.....
# And finally the routine which starts the fcgi responder, as user www
os.seteuid(wwwuid)
WSGIServer(request_handler, **wsgi_opts).run()
....

The complete script you can get at:

It is a simpler server than for example django if you want to understand
fastcgi. By the way the aim is to display  the FreeBSD ports trough
a fastcgi responder.
