I was wrong. I did confirm what code was causing the issue. In my servlet at
the top I did this:
cookie[index].setMaxAge(0);
resp.addCookie(cookie[index]);
Then at the bottom of the code I did:
resp.sendRedirect(".....");
When I commented out the code relating to the cookies it then worked. I
believe that if you call resp.sendRedirect you may not be able to do anything
else with the resp. This is just a guess.
You might be able to do things with the response *if* the response has
not been "committed". A response is "committed" when the first bytes --
usually the full set of headers and possibly some of the response body
-- have actually been sent to the network interface.
Once that happens, the only thing you can really do is destroy the
response body and show the user an ugly page.
None of this stuff is related to your original report of AJP errors.
Check the max_packet_size on httpd and the packetSize in Tomcat, as Mark
suggested.
We recently upgraded from Tomcat 8 -> Tomcat 9 in production and we were
surprised to find similar errors in spite of configurations that should
have been identical to our previous version. A re-sync of the packet
size configuration got everything working perfectly again.

I think I might have found the issue. I built my web app with Java 8 and
Tomcat 9 using version 4.0 of the web-app species originally. This was a
servlet mapping I had:
<servlet-mapping>
<servlet-name>NavigationServlet</servlet-name>
<url-pattern>*.navigation</url-pattern>
</servlet-mapping>
Notice the url-pattern. It has *.navigation.
Now I am using Java 17 and Tomcat 10.1 with version 5.0 of the web-app specs.
Is the above allowed with a URL redirection?
Yes.
I think the *.xyz might be the issue with HttpServletResponse sendRedirect .

Unlikely related given the error you are seeing.

Apache Web server communicates with an application server running tomcat. The
application name is webtools.
I am migrating a working app from Tomcat 9 to Tomcat 10.1.
Does your AJP connector in Tomcat 9 have a packetSize attribute? If
yes, you need to copy that across to 10.1
You can also check your work configuration on httpd for max_packet_size.
The two values have to agree.

I am getting this error in the tomcat app after sending a web request. It seems
like it is starting to load things. Then I see the below:
