WebRTC stream suddenly stops working from time to time

Hello, I'm using go2rtc to get the stream of a Reolink Doorbell camera, and then I consume that from HomeAssistant. It works for about a week, and then it usually crashes and stops working, so I have to restart the server manually.

This is the config:

api:
  listen: "0.0.0.0:1984"    # default ":1984", HTTP API port ("" - disabled)
  username: ""  # default "", Basic auth for WebUI
  password: ""   # default "", Basic auth for WebUI
  origin: "*"        # default "", allow CORS requests (only * supported)

streams:
  doorbell-sub:
    - rtsp://user:pass@192.168.2.102:554/h264Preview_01_sub
    - ffmpeg:doorbell-sub#audio=opus#audio=volume

ffmpeg:
  bin: ffmpeg  # path to ffmpeg binary
  volume: "-af \"volume=10\""

And then this is what I'm seeing in the info page of that stream:

We can probably remove HomeAssistant from the formula, because although that's what I'm using to consume the stream, if I go to the go2rtc panel, and click on stream it also fails to load, it keeps loading forever.

It looks like the websocket connection is not responding, maybe ?

So many childs is a big problem. Don't know yet why this can happen.

I can provide some more details:

I'm currently using version 1.9.6, before I was using version 1.8.2, and this issue was not present
Most consumers are mobile, using HomeAssistant app, specifically iOS devices
The common use pattern is: open HomeAssistant -> tap on a button to show the Camera dashboard -> then move to another iOS app. The HomeAssistant app is usually not explicitly closed

I can also send you the HomeAssistant card configuration in case it helps, but I believe it's pretty straightforward

type: custom:webrtc-camera
url: doorbell-sub
mode: webrtc
media: video,audio

So many childs is a big problem. Don't know yet why this can happen.

Its related to self referencing streams i think which should be fixed in v1.9.7. After closing the stream, the rtsp consumer from ffmpeg is still present. And if there is an issue with ffmpeg, the childs are not cleaned up

I can try upgrading to v1.9.7 and check if it happens again. I'll let you know in a few days

@AlexxIT @seydx I've upgrade to v1.9.7 and the same thing happened again
