MDM Trouble Report for 2007 Oct 24 Telescope: 1.3m Observer(s): Eastman (OSU) Instrument: 4K Problem(s) Encountered: Mcgraw hung again as I was taking dome flats. When it was about done writing an unbinned flat to the disk, mcgraw froze. The mouse stopped responding and I couldn't ssh to it from hiltner. I did a hard reboot. On restart, I did a recovery following Rick's procedures. The strange thing was that there was a partial image on McGraw (4kdayflat071024.0033.fits renamed to .bak) that it was presumably writing when it crashed, but the recovery procedure got both 0033 and 0034 from Caliban. These were 100 second unbinned exposures, so it seems odd to see a race condition here. When I restarted prospero, 0035 was the next one in the sequence. ------------------------------ Submitted on 2007 Oct 25 [8:25:18]
