Container using about 4% of CPU constnatly when idle

[p4xel]

Steps to Reproduce

I reinstalled docker container with default configuration.
My docker-compose looks as follows:

---
services:
  unmanic:
    container_name: unmanic
    image: josh5/unmanic:latest
    ports:
    - 9889:8888
    restart: unless-stopped
    environment:
    - PUID=1029
    - PGID=65537
    - TZ=Europe/London
    - LIBVA_DRIVER_NAME=i965
    volumes:
    - /volume1/docker/unmanic/config:/config
    - /volume1/docker/unmanic/tmp:/tmp/unmanic
    - /volume1/tv:/library/tv
    - /volume1/movie:/library/movie
    devices:
    - /dev/dri/renderD128:/dev/dri/renderD128       # For H/W transcoding using the VAAPI encoder
    - /dev/dri/card0:/dev/dri/card0
    healthcheck:
      disable: true
    networks:
      custom_net:
        ipv4_address: 172.18.36.10
    
networks:
  custom_net:
    driver: bridge
    ipam:
      config:
      - subnet: 172.18.36.0/24
        gateway: 172.18.36.1

Expected behavior: Idle CPU usage <1%

I tried to disable everything, including file monitoring for library, but the issue still persists.

Experiencing similar issue on bare metal running dockerized unmanic

Worker Count: 3
Workers State: Paused
Workers: Scheduled 1AM-5AM
Pending Task: Null

Same, averaging 3.8% of my cpu when idle, I have file watching turned off and just one worker.

[rs443]

Same issue here. Unmanic-service idling at 4-8%. 1 worker (scheduled and paused) and 1 library with library monitor turned off.

Docker on bare metal Ubuntu Server.

Setting update interval in cpu usage updates you can see that unmanic-service jumps between 0 and ~30% cpu every second. Does the service/monitor need to be this aggressive while the workers are paused and/or idle?
