The image processing stops working without any reason

[CarpeDiemRo]

Environment

1. RPI 4B, 8GB
2. NCS2
3. HA core-2021.3.4
4. HA installed in Docker, Deepstack installed in Docker
5. Six analogic cameras 1920x1080

Automation

1. Trigger when movement and /2 seconds during movement = true

Actual results

1. Unknown status is displayed instead of the value
2. All the camera image_processing.xxx.yyy fails and shows Unknown status

What I tried

1. Trigger manually all the cameras
2. No effect
3. sudo reboot -> the service is running again.

OBS I am unable to reproduce manually and I didn't identify a root cause Unfortunately, I lost the logs, but as far as I remember showed something related to prediction

This is an issue on the deepstack side, please report there, although without logs this is a dead end for a maintainer
