I have the same problem and I think it all began when I introduced virtual hosts in
Tomcat. But if you say that you replicated all relevant files to another machine, then
it can't be anything from Tomcat's configuration.
Digging through sources gave this result:
- Apache process/thread tries to connect
- It hits Tomcat and gets handled by methods in warp.jar
- The method for handling initial Warp connection recieves a "registration" from
Apache
- That "registration" contains Apache's virtual host name (or ServerName)
- The method tries to register this connection in the Container
- It synchronizes on the Container object, checks to see if there is such a child
- If not, it registeres it with "addChild"
This is where things go wrong, because addChild runs into that particular child and
fires the exception.

I have tried it on two of my Digital UNIX machines, same error.
Nix.
