Yes, as a matter of fact... I use portupgrade with FreeBSD, and I gave it the -fRr flags which forces the upgrade (recompile), even if the version is the most current, and also recompiles all other packages that 1) depend on Apache, and 2) Apache depends on.

What is odd about that suggestion... I thought of that, too.... I previously dropped the mod_security module because of some strange error log entries (although mod_security seemed to perform correctly). I commented it out of the httpd.conf file to see if that stopped the error entries. It did. But it also started causing the new/worse problem. Putting mod_security back into httpd.conf brought back the strange log errors, but at least it's not sucking up all the CPU (for now!).
Also, as was suggested (SORRY this is so long):

Well, I backed down to 1.3 and everything is back to normal. I didn't have to change versions anything else, so that was nice. I'm not sure what went wrong, but version 2 just never really ran quite right (either that strange mutex error, or the hanging). It would be nice to know what was causing that, but it's probably way beyond my ability to figure out. And the problem with bouncing around with versions is the downtime. Not much of it, and it's not a very mission critical server, but people do miss the sites when they are offline.
Thanks for everyone's help and ideas,
Chris

That is not really an error, but simply "info". It means that a
client disconnected before all the data was written (stop button
pressed or some such thing).

That would just be a shot in the dark. I would try first to look at
some other core dumps. The one you posted was the problem you had
restarting apache. It doesn't say anything about the problem that
caused running processes to die.
Personally, I wouldn't be surprised if there was some deaper problem
in your system.

I've noticed a pattern, for what it's worth.....
I see this in the httpd error log, usually within about an hour from when httpd starts sucking up all the CPU:
[Fri Jul 16 10:29:14 2004] [info] (32)Broken pipe: core_output_filter: writing data to the network
Based on the unixd_pre_config having to do with suexec, should I do away with suexec completely, and see if that helps?

I have no idea. That's pretty odd. The only thing that
unixd_pre_config does is stat the suexec binary to see if it exists
and is suid. Why that would result in a call to libXext, I don't
know. I also have no idea what event_to_wire is.
