I'm not sure the exact way to repeat the problem but seems to occur if pause is attempted while the guide camera is operating, So to repeat the problem I had the guide camera looping. This occurred on another system as well. We both had the same setup.
attached is the log where the problem occurred twice.
Here is another set of logs. The problem occurred after completing the capture sequence when I tried to restart it. I believe I need to both have the guide camera operating and pause the capture. When the capture was complete and I tried to restart it, the capture hangs. If I abort and restart again it hangs again. I have to disconnect and restart the drivers to clear the problem. Here is a couple of screen shots too showing the restart windows and the status when hung.
