Whenever I got this message it was always caused by wrong interview data. ZWay couldn't create a virtual device. In all cases these data were unnecessary and suddenly appearing without known reason. A new interview repaired it.

As a quick follow up: great suggestion, after re-interviewing that device the error hasn't popped up again. Before that I showed up reliably every 20 minutes. Once more, thanks!
