Zimbra and Openfire at startup - Conflicting

I am running Openfire 3.6.4 on Ubuntu 8.04. This server also runs Zimbra v6. As of now, the Openfire startup task is disabled as well as the custom startup task I created to start Openfire upon startup…

#!/bin/bash
/opt/openfire/bin/openfire start

When either one of these tasks are set to run upon startup, when navigating to the Zimbra login page, I receive the ‘powered by Jetty; page cannot be displayed’. Once those startup tasks are removed the the server is rebooted, Zimbra comes up OK, even after manually starting Openfire.

Any ideas?
