Overnight results of h1digivideo3 camera stability after 10GE upgrade yesterday

Jonathan, Patrick, Dave:

Around 14:00 yesterday (Wed 06mar2024) we upgraded the camera network link to h1digivideo3 from 1GE TPE to 10GE fiber. After running overnight, all of the cameras on this server are still running and, with the exception of ETMY, no further VALID=0 have been seen (2 day trend attached, upgrade at the 18h mark).

ETMY continues to have an hourly VALID=0 which flashes the camera client images blue-screen for a few seconds. This happens at roughly the 20 minute mark in the hour and it slowly advances through the hour.

The ETMY periodicity is not changed by h1digivideo3 reboots, suggesting it is in the camera itself. To test this, I power cycled the ETMY camera at 08:34 this morning.

Power cycling the ETMY camera (h1cam27) appears to have fixed the hourly blue-screen flashing.

We have had no camera drop-outs or VALID=0 issues over the past 24 hours. Looks like h1digivideo3's problems have been resolved, I'm closing out FRS30615
