Same problem here. My logs are flooded with this error

Code: Select all

Typically that would be caused by a crash. Crashes will be logged. Look in your logs.

Thanks, the problem was a camera that was not connected. Because of this, I got several errors in zm log and then the errors in system log that I reported. I deleted the camera and now I get no more log errors. I thought that disabling the camera was sufficient not to have log errors: it was not.
Is there a way to keep the configuration of a camera that's not connected without deleting it AND without getting errors in the log? Thanks.
