[Support]: Detection process keeps restarting

Describe the problem you are having

Frigate installed on HA running in a VM in DSM 7 on Synology DS920+. I also have a Google Coral USB that I passthrough to the VM. Everything seems to work just fine, but in the log every now and then (15 to 30 minutes) the Detection process appears to be stuck and restarts.

The Google Coral works because I tried to run the Official Google Coral Test in the docker container where Frigate is running (i just needed to install a few dependencies like git and curl). It runs (even if after running the container crashed.

Version

2.3
