We have also problems (Failed requests) :
Tomcat 4.0.4 + Apache 1.3/2.0
Tomcat 3.3.1 + Apache 1.3/2.0
No problem with TCs using their own http connectors.
The Apaches servers setup was to have up to 250 clients.
The Tomcats server allowed up to 250 ajp threads.
That results are really bad, since they show us that under
heavy load mod_jk 1.2.0/Tomcat may miss some requests.
I continue my tests but comments and ideas are welcomed

BTW, I've got the bench for Resin 2.1.2 on same platform
