Problems: 

The observer3 machine froze completely for about 10 minutes during observations today. We managed to ssh from observer2 into observer3 and, after killing all the chrome processes we finally regained control of the machine. After that we were able to reinitiate all the GUIs (with help from Manuel). We didn't loose any exposure during this process because we had about 0.5h worth of items in the queue and although the GUIs were frozen, exposures were still going. We don't know what caused this issue and telops report that it has not happened in a very long time. It is probably a good idea to investigate this further if it happens again. 

We had again the "DONUT" not ready glitch in SISPI. Same of last night. Lost 3 exposures in total due to this. Another side effect of the problem is that the last exposure before the glitch gets repeated.
