I seem to have a strange problem, that can best be reproduced by this

curl http://www.geobaby.com/calendar/ -- works (connection terminates and control returns back to the prompt)
wget http://www.geobaby.com/calendar/ -- does not return control

In firefox, the page does not seem to load although I can view the source.

Any clues as to where I could start debugging?

Nginx:
./nginx -V
nginx version: nginx/0.8.11
built by gcc 4.1.2 20080704 (Red Hat 4.1.2-44)
configure arguments: --prefix=/usr/local/nginx --with-file-aio --with-http_realip_module --with-http_geoip_module

PHP-FPM : 5.2.10
