If you take a look at this thread, you'll see I'm providing more data to Tim on the DDW driver. Yet another case where the driver is coming up short:

But I do have one Scheduler question. At 6:00 a.m., Scheduler sends a shutdown command. But when I woke up at 7:00 a.m., the ACP window says "Dome Closing".

So why did Scheduler/ACP start a shutdown command, and leave the state as "Dome Closing" without noticing that the shutdown sequence was stuck and send a "Fatal" message that operator intervention is necessary? The dome was hung up, but Scheduler/ACP did not take action. At present, if the "Fatal" email went out, I would have gotten a text message and two phone calls (landline and mobile).
