I've taken httpd on axkit.org down permanently for now, until I can figure out what the heck is up with it. I've now had to reboot twice. Last time I could see it, there were about 50 httpd's spawned (which is a lot when each uses mod_perl and about 15M of ram!), and all were using 100% of RAM. I swear all I did was restart the httpd after deleting a bunch of log files.
However, I can see how a restart might potentially affect things - if I did a apt-get upgrade (which I did) a few weeks ago, but hadn't restarted my httpd since, it might change something that could cause this.
So I'm a bit lost now. How do I fix it? I have absolutely no idea what to do right now. I tried the old USR2 signal trick, where you install a signal handler to do a Carp::confess, but that failed to work (nothing appeared in my logs).
Yours bogglingly, Matt.
