Some cameras on h1digivideo3 have become unstable recently
Patrick, Jonathan, Erik, Dave:
We are working on an issue with some cameras on the new video server (h1digivideo3) becoming unstable over the past few weeks, resulting in their images going blue-screen until their server process is restarted.
I've opened FRS30615 for this issue.
As part of this investigation, yesterday we removed the first camera service from h1digivideo3 (FC TRANS-A IR) because its camera is not working. We were hoping reducing the cpu loading would make the other camera services more stable.
This resulted in the EDC disconnecting from the 20 channels associated with this camera. To "green up" the EDC, I am running a dummy IOC on cdsioc0 which serves these chans (tmux session called cam_fc_trans_a_dummy_ioc)
We also rebooted h1digivideo3, which had been up 190days.
Neither of these fixed the problem.
