Are you behind a firewall by any chance? – noticed that in my setup (it’s a new one day old installation) that when you post a comment wordpress seems to want to connect to the following site, sosocrates.scdns.net, lsof output attached:
TCP 172.16.10.1:35246->socrates.scdns.net:http (SYN_SENT
Since I’m behind a firewall the connection above never completes & times out – the timout (1 to 2 minutes delay) is causing the 404 error?
