I'm having an intermittent squid issue. It's plagued me with CentOS 5.x, Fedora 6, and now Fedora 11 (all using the RPM build that came with the OS).
My DD-WRT router forwards all of my outgoing port 80 requests to my transparent proxy using IP tables. For some reason, squid will hang when opening a URL for up to two minutes. It doesn't always happen and sometimes restarting squid will correct the problem (for a while). The system is pretty hefty 3ghz P4 with 2G of RAM with a SATA II drive. That should be plenty for a small home network of about 10 clients.
When I test DNS lookups from the host, requests are returned within less than a second. I'm pretty sure that's not the problem.
Here is my squid.conf, any input would be greatly appreciated!
