[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Native APR, SSL and a multihomed machine

I have a multihomed server on which I have installed two identical versions of JBoss 4.2.0.  I have also installed JBoss native on each in order to use the Tomcat APR optimizations.  I also set up an HTTPS connector on each server.  I use the -b option on each instance in order to bind it to a dedicated network card.  Running each server by itself prevents no issues.  When I try to start the second server when the first is already running, I get a port binding error (the port configurations on each instance are identical, since they will be using a different NIC).

A little investigation reveals that the HTTPS connector is listening on all available IP addressed.  Thus when the second server starts, it fails to bind to the HTTPS port.  When I adjust the HTTPS port on the second server I no longer get this error.

Is there a configuration beyond the -b start up parameter I should be using to prevent the SSL connector from listening on all IP addresses?

The configuration for the connector, as detailed at http://tomcat.apache.org/tomcat-6.0-doc/apr.html, is below:

  |     <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
  |                maxThreads="150" scheme="https" secure="true"
  |                clientAuth="false" sslProtocol="TLS"
  |                SSLCertificateFile="C:/certs/cert.pem"
  |                SSLCertificateKeyFile="C:/certs/key.pem"
  |                SSLPassword="notmyrealpassword" />
