At 16:14:31 PDT h1daqdc0 crashed. Its EPICS IOC stopped running resulting in white boxes on MEDM. Last log was 15:56.

I connected a monitor to its VGA port, its console was showing the login prompt. The cursor was not flashing and an attached keyboard was unresponsive.

Erik and I rebooted the machine by pressing the front panel RESET button. It booted and started with no problems.

Currently we don't know why dc0 froze this way.
