1. Please provide your definition of "haywire"

2. Do you have Apache HTTPD in front of Tomcat ?  Do you use mod_jk?

3. Your operating system, and what versions of the mentioned software
you are running.
How old is your Tomcat 5? You may want to look at

Also Java 4 has already reached its EOL.

Usually older apps run fine on Java 6, and Tomcat 5 apps run fine when
deployed on Tomcat 6,  and two instances of Tomcat, be them of
different or of the same version, run fine with each other.

4. What do you mean by "8085-8100"
