I tried your fix, and it didn't fix it for me.

Does anybody else have any ideas?

With less than two minutes left in today's workday, on a hunch I
disabled the default ipchains startup using
'/etc/rc.d/init.d/ipchains stop', re-ran all my mrtg configs, and
no more timeouts occurred.

It was a nice way to end the day; now we'll see how well it
worked when I come in tomorrow morning.  =)
