High CPU load while apparently idle

Expected Behavior
While not being actively used or doing housekeeping (i.e. scanning etc) it should run with negligible CPU load like any other Docker container
Current Behavior
It runs with up to 100% of a full core:
Steps to Reproduce
- start the docker container any way you like.
- monitor logs, wait for all the initial housekeeping to complete
- start a cpu monitoring program like top
# top -c -d10
top - 14:01:29 up 12:19, 1 user, load average: 1.77, 1.25, 0.73
Tasks: 224 total, 1 running, 223 sleeping, 0 stopped, 0 zombie
%Cpu(s): 26.4 us, 0.4 sy, 0.0 ni, 73.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st
MiB Mem : 923.1 total, 39.1 free, 457.3 used, 426.7 buff/cache
MiB Swap: 1024.0 total, 767.4 free, 256.6 used. 405.5 avail Mem

I realize this is "only" a tiny RPI 3B+ with very limited resources but notice the number of containers running, yet none of them appear in the top-10 CPU consumers. All containers perform absolutely acceptably when used, even Emby when not having to transcode to a webapp.
Environment
OS: Raspbian GNU/Linux 11 (bullseye) armv7l
CPU architecture: BCM2835 (4) @ 1.400GHz ( Raspberry Pi 3 Model B Plus Rev 1.3)
How docker service was installed:
From official repo, as per standard RPI guidelines. (curl -fsSL https://get.docker.com -o get-docker.sh)
Command used to create docker container (run/create/compose/screenshot)
docker-compose.yml:
