It works in the sense that I can run genmap from the command line with
python2.4, but I still get the same errors in error.log, and a 501 when
calling genmap.fcgi from the browser:

[Mon Feb 12 10:43:09 2007] [warn] FastCGI: (dynamic) server
"/var/www/mapit/genmap.fcgi" has failed to remain running for 30 seconds
given 3 attempts, its restart interval has been backed off to 600 seconds

I wonder if "dynamic" is the right mode to run genmap? If I understood
that right there are three modes to run fast-cgi scripts, do I have to
choose a particular mode?

Anyway, I wrote a small test script (with code stolen from genmap.fcgi)
to see if fast-cgi generally works for me, and it does.

Best regards,
Moritz

P.S. this is the test program that works fine as fast-cgi script.

#! /usr/bin/python -O
import os, sys
import socket
import fcgi

def main():
    while(1):
        try:
            while fcgi.isFCGI():
                req = fcgi.FCGI()
		print "Content-Type: text/plain"
		print
		print "Something"
                req.Finish()
        except socket.error:
            continue

        except Exception:
            break

main()
