nginx error 12: Cannot allocate memory

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.

Version of frigate frigate:0.9.0-rc2-aarch64

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"
}

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

Thanks.
