Sending a new sample of code after I started parallels everything jammed again. You should look into it seriously since it may take a long time before it gets back to normal. Lots of time lost here... Processor was at 196% for a long while.
Just sent my technical report # 335593968 about this same issue. In this situations, I observed over 100% processor use by "Windows 10" and "Windows Server" in the Ressource Monitor. I also added a sample from the ressource monitor.
