Thanks for reply. As a matter of fact, right after sending my question, I realized that a bug in the installation code ended up adding another connector with port number zero which wasn't in the original server.xml. Problem resolved.

I am not aware of automatic connector creation except if using embedded, but that doesn't look to be your case here with that server.xml fragment. Any other information ?
