You have two of them. Whether they are really irc connections can't be
said from that. The "ircd" comes from /etc/services and so port 6667 is
translated this way. But it is:

Trying 12.5.48.98...
Connected to ftp.pqa.com.

I can imagine that this does not show something useful. I guess there
are cgi::irc webchat interfaces running. So check the content of cgi-bin
directories. These webchat things can consume large amounts of
resources.

So you have users allowed to run things on Apache?

locate irc.cgi

Maybe that shows you quickly the locations where the "bad" things are.
