This afternoon, while I was trying to add the StochMon channels to the frames, I rebooted the c1ioovme and c1iool0.
I had to do it twice because of a mispelling in the C1IOO.INI file that the first time prevented the computer to restart properly.
Eventually I restored the old .ini file, as it was before the changes.
After rebooting I also burtrestored.
During the process the mode cleaner got unlocked. Later on the autoclokcer couldn't engage. I had to run the MC_down and MC_up scripts.
