Apache Tomcat error re: port 8080

Hello.

Our environment:

• RoboHelp Server 8.0
• Apache Tomcat 6.0.26
• Windows Server 2008 enterprise without Hyper-V SP2  (32-bit virtual machine)
• RoboHelp 8.0.2.208

Our help system is periodically non-responsive. The Apache logs (extract below) indicate that there is an application using port 8080. We (my IT support and I) discovered that RDP (Windows Remote Desktop) had been changed from port 3389 (its default) to port 8080. The server is dedicated to our help system; there isn't anyone touching it so we were a bit confused. We reset the RDP port back to 3389 and restarted the server (full server restart) and everything worked as it should. A couple of days later...the same thing...and then a few times in one day. Research indicates there may be some Windows or Apache bug related to ports being reset to 8080, but not a lot of detail or suggestion for resolution or work around.

Has anyone experienced this port issue?

I am not familiar with Apache...is there another port that it can use and still run the RoboServer?

Any thoughts or suggestions re: how to proceed?

TIA,

Michelle
