Massive performance degradation

Expected Behavior

Server minimally affected by nzbget container.

Current Behavior

As of the beginning of last week, the nzbget container causes huge performance loss in network connectivity to my server. SSH and other containers which depend on network bandwidth slow to a crawl. To test for the offending container, I tore my docker-compose.yml down to a minimum of containers and added a container back each day and observed the results. After 4 days and 4 containers, I put up NZBGet and can see a clear correlation between it and ssh access times over one minute, other containers like Synapse timing out, etc.

Steps to Reproduce

1. Run NZBGet latest tag.
2. Observe over the next few hours as your server shits the bed.

Environment

OS: Synology DSM 6.2 CPU architecture: x86_64/arm32/arm64 x86_64 How docker service was installed: DSM provided.

Command used to create docker container (run/create/compose/screenshot)

  nzbget:
    image: linuxserver/nzbget
    container_name: nzbget
    hostname: nzbget
    restart: unless-stopped
    networks:
      - t2_proxy
    ports:
      - "6789:6789"
    volumes:
      - $USERDIR/docker/nzbget/config:/config
      - $USERDIR/downloads:/downloads
      - $USERDIR/docker/nzbget/intermediate:/intermediate
    environment:
      PUID: 1037
      PGID: ${PGID}
      TZ: ${TZ}
    labels:
      - "traefik.enable=true"
      ## HTTP Routers
      - "traefik.http.routers.nzbget-rtr.entrypoints=https"
      - "traefik.http.routers.nzbget-rtr.rule=Host(`nzbget.$DOMAINNAME`)"
      - "traefik.http.routers.nzbget-rtr.tls=true"
      - "traefik.http.routers.nzbget-rtr.tls.certresolver=default"
      ## HTTP Services

I'm afraid Run latest tag and observe over the next few hours as your server shits the bed. do not qualify as proper steps to reproduce

Open to suggestions as to what qualifies. I know it's nzbget that is the source of my problems and I have attached a copy of my logs.

Is nzbget doing anything?

According to the logs it had grabbed "The Bachelorette" (yes yes I know it's embarrassing) but looks like it found it unhealthy and bailed.

EDIT: there's also repeated rejected connection attempts to one of my news servers.

I continued to throw myself against the rocks on this one, finally finding an enabled-by-default setting for Energy Efficient Ethernet which turned out to be the culprit.
