Actually, this machine's behind a firewall, and I am the only one hitting it. It's got alot of RAM and isn't even close to running out. I have resolvenames turned off, but I just did a tcpdump and it *IS* trying to connect to a DNS server outside the firewall, which is blocking the request. I think that's my problem.
