Reboot of op440m
I was reviewing the PSL Overview screen this afternoon and op440m completely froze when I center-clicked on the REF CAVITY TRANSMISSION indicator. It was unresponsive to any keyboard or mouse control. The moon button had no effect to shut the machine down.
Called Alberto in and we logged into op440m from rosalba. From there we logged in as 'root' and run a shutdown script '/usr/sbin/shutdown -i S -g 1'. The medm screens started disappearing from the op440m display and we were eventually asked to enter System Maintenance Mode. From here we selected RUN LEVEL 5: "state 5: Shut the machine down so that it is safe to remove the power". Following this the machine turned itself off.
We powered it back on, logged back in as controls and restarted the medm screens. Everything seems to be running fine now.
