Upon an event, I start a bash script that sends an email, voices a message via Amazon Echo and sets the IPCAM to None. I use REST API to make the IPCAM change. The syntax works fine when I run it independently or manually start the script under user www-data. It does not seem to work when ZM starts it. It does all the tasks except turn off the IPCAM.

I get this error:

Appreciate any guidance. If more info is needed, let me know.

Stating the bleeding obvious, the DB can't keep up.

I think I've solved the problem.

The script gets the status of the camera (using curl and REST API) before changing the setting. I believe the first curl command was hanging which might have kept the record locked. I added to the curl commands "-m 2" which sets a time-limit of 2 sec. My test shows this now works.

That's good. Well deduced.
