Thanks for your suggestions. The app is Avizo and the issue is that on startup it interrogates the driver in some way to determine the amount of vmem in the system which fails under VNC. When such a zero value is returned the app then defaults to 4GB present. The vendor supplied me with an environment variable which can override this value.
