Not able to create connections to http://dmoz.org/http://www.dmoz.org/Health/Mental_Health/Disorders/Impulse_Control/Kleptomania/ from your server.
The reason might be a firewall, proxy, or http://dmoz.org/http://www.dmoz.org/Health/Mental_Health/Disorders/Impulse_Control/Kleptomania/ or your web hosting company might be blocking outside connections.
Another possibility is a timeout because of slowdown in internet itself.
