High cpu usage on scylladb on idle

[baronets-turk]

Describe the bug

I noticed that in my docker compose out of many other dependencies scylla database consumes 100% of one cpu right after the start on idle (without any payload). Same config on docker desktop consumes near to nothing.

To Reproduce

1. Run docker compose up scylla1 -d with config

services:
  scylla1:
    image: scylladb/scylla
    container_name: scylla1
    hostname: scylla1
    restart: always
    ports:
      - "9042:9042"
    volumes:
      - scylla1-data:/var/lib/scylla
    environment:
      - CLUSTER_NAME=scylla
      - SCYLLA_SEEDS=scylla1
    command:
      - --authenticator
      - PasswordAuthenticator
      - --authorizer
      - CassandraAuthorizer

volumes:
  scylla1-data:

2. Run docker stats --format "table {{.Name}}\t{{.Container}}\t{{.CPUPerc}}" to the the load:

NAME      CONTAINER      CPU %
scylla1   9d42c55f2f3c   101.07%

It stays the same around 100% all the time

Expected behavior

On docker desktop it consumes a far less cpu:

NAME         CONTAINER      CPU %
ja-scylla1   0ea14890114c   4.50%

Tried that and could not reproduce:

NAME      CONTAINER      CPU %
scylla1   f88205c6a8e4   4.41%

Checked the activity monitor and there was no high CPU usage for OrbStack processes either.

What if fix version of scylla? It's ok for me with 5.2 version, but consumes a lot of cpu on latest (5.4):

services:
  scylla1:
    image: scylladb/scylla:5.4.6
    container_name: scylla1
    hostname: scylla1
    restart: always
    ports:
      - "9042:9042"
    volumes:
      - scylla1-data:/var/lib/scylla
    environment:
      - CLUSTER_NAME=scylla
      - SCYLLA_SEEDS=scylla1
    command:
      - --authenticator
      - PasswordAuthenticator
      - --authorizer
      - CassandraAuthorizer

volumes:
  scylla1-data:

Tried 5.4.6 tag and the CPU was still around 5%. Even tried linux/amd64 (platform: linux/amd64) image and the CPU usage was around 10%.
