Instructions for Restarting the PyWFS camera (Saffira): (from Sylvain)
Symptom: PyWFS Camera (in the PyWFS status) shows red and says it is powered off
Clicking on it and rebooting/restarting the camera server does NOT resolve this.
Solution:
Connect to the RTC: ssh -X prtc@prtcserver
showRTProcess: it opens a window and the 2nd process from the top is partially crash
Ctrl-c to restart the process
Then connect to: ssh -X pwfs@vm-pwfsserver
Issue command: prtcRestartCOM (takes about 5 sec, then you should be able to reacquire the camera)
