I actually upgraded from mod_jk 1.2.26 to 27 to try and make the
problem go away.
I see the mixup in the file sizes so thought a trace was not necessary.
The mixup occurs only in tomcat originated data - the static stuff
coming from httpd stays fine.
Moreover, in the past I had it setup so the static stuff came from
tomcat as well. This naturally resulted in significantly more hits
between apache and tomcat which made the problem appear much faster
(hence my theory that some resource is being depleted over time).

So, when your site goes crazy, a simple httpd-bounce does the trick? No
Tomcat restart or anything required? Existing users and sessions are all
preserved and pretty much the problem just magically goes away?
Crazy.
I see that you are using httpd 2.2.10. Have you tried downgrading to
2.0.x to see if that helps? I've heard some folks having trouble with
mod_jk 1.2.27, so you might try downgrading to 1.2.26 unless something
vital is in the .27 release that you need.
Those are easier fixes than switching to proxy_http or removing httpd
altogether.
If you watch the network traffic with a TCP sniffer like wireshark, does
it look like request A results in response B instead of (expected)
response A? When the server goes crazy, can you start sending TRACE
requests to see if those get mixed-up? Does all traffic get jumbled, or
just the stuff bound for Tomcat?
