Ray,
10 minutes ago the server wasn't accepting connections and now I arrive at
the server's location and it's working again. So the output I provide
(somewhere below) might be different when it's not actually working.

The errors were usually coming almost instantly.
Host name lookups are not enabled for Apache.
Here's the authentication portion of inetd.conf:
# Authentication

auth stream tcp nowait nobody /usr/sbin/in.identd in.identd -l -e -o

The swap partition is 128MB. I can log in and start processes normally
locally. (Once before, when the server was rejecting connections, I could
also log in and start processes locally.)
Here's the output of free: (Of course, the server is actually working
right now!)

I can create new files and start new processes.
Thanks again!
