Bill,
Thanks again for this tip. After reading the document to my best ability, I added this line to the end of /usr/local/tomcat/common/classes/logging.propeties :
org.apache.jk.common.MsgAjp = ALL
I got as a result what seemed like no logging at all for this class.
I am setting it to DEBUG now to see what happens, but am I doing this correctly at all?
Thanks for your help,
Collin

Thanks so much for replying! I can understand that concept. Given that
we are using mod_jk to connect the Apache frontend to Tomcat running
OpenCMS on the backend, perhaps the way that the application is working
that is giving us this result?  Also in response to Bill, where can one
turn on
DEBUG logging for a specific class such as

org.apache.jk.common.MsgAjp


?

I'm thinking that would be in one of the xml config files and I will do
more research on that, but if you had a quick answer, I'd be happy to
hear it.
On the suggestion of Mladen Turk, I did upgrade to mod_jk 1.2.14, I hope
to see some difference there.
Thanks again,
Collin

The message is simply that you have a header value that is too big
for the
AJP/1.3 protocol to handle.  If you enable DEBUG logging for
org.apache.jk.common.MsgAjp, you should get a dump of the partial
data that
should include the name of the bad header.
Given the line, it could be a monster header value, possibly a cookie
(the size is 18KB, which is way over the AJP/1.3 capabilities).
