Just a couple of ideas... - DNS: is it working? If apache needs it to resolve IPs (eg, if you have VH tags containing a domain instead of an IP) and it isn't working, apache can get stuck. - Hanging forever is sometimes due to an errant firewall - it silently drops the packet rather than refusing the connection, that way an attacker can't distinguish between active security and network latency. Did you enable/adjust the FW (ipchains?) on the server? - you have: apache + server_1 = broken, apache + server_2 = works therefore server_1 != server_2 So what changed on server_1? Any chance of a re-install?
