modwsgi

When you say the wget fails on the first request, are you saying the
blank page problem only ever happens on the home page of the site?

BTW, I have seen some reports of MacOS X having strange network issues
which might partly explain this. I can't remember though if it only
caused problems when the web server itself was on MacOS X. If I can
remember what was being described and where I saw the posts I will
send them around.

What OS type are you running the Apache web server and wget on? Is
Safari browser on MacOS X the only place you have got error response.

Finally, check both main and virtual host error logs for any instances
of 'Segmentation fault'.
