Carlos, Dave, Stefan:

earlier this afternoon digital video cam04 (ALS X) and cam18 (AS AIR) developed problems. Through a combination of power cycling the cameras (via POE on the network switch) and restarting the python programs these were recovered. This evening Stefan found cam22 (ITMX Green) also had an issue. Its image was changing, but its corresponding epics channels were not updating and the date/time on the image was frozen. We tried restarting the CAM22 process on h1digivideo2 (manually and via monit-web) but the issue did not clear. I then rebooted h1digivideo2 (it had been running since 06Jun2016) and the problem cleared. We saw CAM04 had developed the problem again, so I rebooted h1digivideo0 which cleared this. We decided not to reboot h1digivideo1 as its cameras are working correctly.
