BS Camera code repeated crashing

For the last ~2 hours the BS camera code has been repeated crashing, bringing us out of Observe, then coming back and having us go back into Observing for a short time and then repeating. It looks like it finally died for real this time and I can't bring it back via Monit. I'll continue to look into how to restart this.

Looks like this happened just the other week - alog73749

I'll get Dave involved here in a bit.

Back to Observing at 1523UTC. Erik will post an log with more info on the camera, but it looks like the same fix that's listed in the above alog.

The fix was indeed the same as the previous alog.  The steps have to be done in the proper order: first restart the camera, then restart the camera server.

1. Restart the camera by cycling power on the port: Log in to the switch, sw-lvea-aux.  Log in either directly from instructions in the password file or from cdsmonitor.

   Once logged in to the switch, these commands will reset the camera.

   a. config t

   b. interface gigabitEthernet 0/35

   c. shutdown

   d. noshutdown

 

2.  Reset the server by logging into h1digivideo2 as root and killing any process named H1-VID-CAM26.  The camera number can be had from the CDS->Digivideo MEDM screen.
