nginx error 12: Cannot allocate memory

[FM-17]

Describe the bug
Frigate 9.0+ is failing to start due to an nginx related memory error on my Google Coral Dev Board. Frigate 8.4 runs fine. This is my first attempt at frigate so I apologize if this was caused by a minor oversight.

Additional context
I am starting Frigate from a docker container using the following docker-compose config:

version: "3.9"
services:
  frigate:
    container_name: frigate
    image: blakeblackshear/frigate:0.9.0-rc2-aarch64
    privileged: true 
    restart: unless-stopped
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - $FRIGATE_DATA_PATH/config.yml:/config/config.yml:ro
      - $FRIGATE_MEDIA_PATH:/media/frigate
    ports:
      - "5000:5000"
      - "1935:1935" # RTMP feeds
      - "1883:1883"
    environment:
      FRIGATE_RTSP_PASSWORD: $FRIGATE_RTSP_PASSWORD
      FRIGATE_RTSP_USER: $FRIGATE_RTSP_USER

My /etc/docker/daemon.json file is as follows:

{
    "default-shm-size": "256M"
}

[blakeblackshear]

It's probably some kind of issue with the custom nginx build that is not compatible with the Coral Dev board. This happened once for another dependency. It's virtually impossible for me to track down without having a dev board.

[FM-17]

Right on, is there anything I can do to lend a hand, given that I have a dev board?

[blakeblackshear]

My best guess is that something needs to change here: https://github.com/blakeblackshear/frigate/blob/release-0.9.0/docker/Dockerfile.nginx

[FM-17]

Sounds good, I'll take a look.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

maybe the memory is allocated by VOD on the coral-dev-board since 0.9x.
and maybe it oculd be configured to give up that allocation

[nickrout]

Does anyone know if this has been fixed? I am keen to try frigate, but the only corals I can find are dev boards. GRRR global chip shortage

[ozett]

up to now unchanged, i guess.
latest 10-beta 6 seems still to have a unchanged high vod value in the sourccode...
