I was dealing with an issue where the USB thumb drive after a while wasn’t recognized by the OS for some reason.
For a while I couldn’t figure out what was going on, because the owl service would fail/stop. After looking at the logs, there was a clear message that there was an issue with the USB thumb drive. That pointed me to the right direction.
I ended up moving it into a different USB port and it looks like the issue is gone.
My understanding is that when the service can’t read the USB storage, it fails or stops working.
I am wondering if that’s by design. If you want to start recording at some point, it would be an issue. However, I wouldn’t stop the owl service just for that reason.
Maybe a warning on the dashboard about the missing/failing USB thumbdrive would be helpful.
