Screenshots of the Frigate UI's System metrics pages

Any other information that may be helpful

I first noticed this when I upgraded from Frigate v0.13 to v0.15.0-beta1, but it has persisted into v0.15-beta4.
(I decided I would skip v0.14 altogether)

The issue usually starts at least 24 hours after starting the Docker container. I can restart the container and everything will be fine... then after a day or so, this error comes back.

Frigate is installed as a Docker container, running on an Apple Mac Mini with Debian installed.
A Google Coral Edge TPU USB is plugged into the computer and Frigate is using that for detections.

Would be great to see the contents of /tmp/cache in the container while this is happening.

Would be great to see the contents of /tmp/cache in the container while this is happening.

Thanks for your reply.

I restarted the container shortly after making this post, so it is temporarily working ok at the moment.

Below are the contents of /tmp/cache/ from just now, so we can establish a baseline. I will post the same output when the error occurs in the next few days.

...and also the number of files in /tmp/cache/:

...nothing really out of the ordinary at the moment. I will report back when the error occurs again.

Thank you.

Ok, after a week without any error, I have experienced the issue again. However, I think I have figured out the cause.

I noted this section in the logs:

Specifically:

[Errno 112] Host is down: '/media/frigate/recordings'

I then checked my NAS logs in Home Assistant, and realised that it had been shut down due to high temperatures (it's summer here) at that same time. And of course, I am an idiot and have Frigate saving recordings directly to a NAS folder mount.

All the other tests came back normal:

...so I am going to assume it's because of the NAS being turned off.

I will now set it up so that recordings are saved locally instead of to the NAS, and will see how we go. I will report back in a week one way or another.

I also see this error on my setup (with 0.15-beta4), seems to be a new thing after upgrading from beta3, but not sure as I had briefly bumped back to stable to check some other instability issues.
What strikes me, is that the camera (reolink 520a) is set to 7 fps, could this be connected to the keeping the 6 most recent segments out of 7 and discarding the rest. ?

[DaveTSG]

Ok, frustratingly, the error hasn't occurred since I restarted the container back on 26th December.
I am now getting different errors in the log file, though, but the video feeds are working fine; I am not noticing any symptoms.

I will provide the entire log since the last container start-up below, but here are the relevant lines:

info | 2024-12-26 16:41:35 | frigate.watchdog | Detection appears to be stuck. Restarting detection process...
info | 2024-12-26 16:41:35 | root | Waiting for detection process to exit gracefully...

info | 2024-12-26 16:42:05 | detector.coral | Starting detection process: 45861

Is this anything to worry about?
(As stated, I'm not seeing any issues, it's just showing that in the log file)

In any case, I will continue to monitor for the original issue and will post a comment if it happens again.

Thanks.

Here's the entire log for the last few days:

I also ran into this exact same issue as described in the original post. My upgrade path has been 0.14.1 -> 0.15.0-beta2 -> 0.15.0-beta3 -> 0.15.0-beta4. However I just started getting this issue two days ago on 0.15.0-beta4. I tried many different fixes (downgrading to 0.15.0-beta3, reducing my camera quality, moving hardware) but nothing seemed to stick. I would start getting the same errors within a few minutes of the container starting. Finally I wiped out my entire media directory for frigate to start fresh (but keeping the config) and I have yet to see this issue happen again.

Ok, as per one of my earlier comments, I had set up Frigate so that the storage/recordings folder was on a network drive (SMB NAS folder, mounted on my Frigate computer). That way, Frigate would save recordings directly onto the NAS.

Good idea in theory. In practice, of course, when the NAS turns itself off, Frigate - understandably - goes haywire.

Making it so that Frigate is storing recordings on the actual computer (rather than the NAS) solved the problem. I was able to test this manually by shutting down the NAS and observing that the error occurred when Frigate was saving to the NAS, but Frigate runs fine when the NAS is shut down if Frigate is saving to the computer instead.

Thanks for helping me with troubleshooting this.
