keyword=DVCS calo IOC reboot and HVI noticed that the run end entries were coming in very late, so then I checked the DVCS calo adc readbacks, and sure enough, they were frozen. So I went to the DVCS how-to page, and eventually found out how to reboot the IOC, However, I mistakenly rebooted all the outlets listed in the instructions at: https://hallaweb.jlab.org/wiki/index.php/DVCS_how_to/#Reboot_calorimeter_VME_ADCs_crate
I soon realized that by doing so I also rebooted all the DVCS HV crates, thus turning off the calo HVs, which was probably not needed. At that point I asked Zein-Eddine to end the run 8936, only a few minutes after I made this mistake.
Now I have restored all the HVs and the ADC readback is working again. Unfortunately, looking back at the end-of-run entries, the IOC was likely frozen since about 1 am (it is 6 am now). Hopefully this will not affect the quality of the data taken between 1:00 and 6:00.
