升级到 rabbitmq4.0 之后，为什么 amqp 连接会每 3 分钟重连一次？

Question

之前使用的 rabbitmq3.x 的，一切都是比较正常

但是升级到 rabbitmq4.x 之后，我是用的 nameko+eventlet+kombu+amqp 就经常会断联（有自动重连机制）

这个比较烦人

出现的断连日志如下：

第一种

Error connecting to broker at amqp://ponponon:********@192.168.38.223:5672// ([Errno 104] ECONNRESET).
Retrying in 2.0 seconds.

我启动 rabbitmq 用的 docker compose

services:
  rabbitmq3-management:
    restart: always
    container_name: rabbitmq3-management
    image: rabbitmq:4.0.5-management
    hostname: rabbitmq3-management-standalone
    logging:
      driver: json-file
      options:
        max-size: "100m"
        max-file: "1"
    environment:
      - RABBITMQ_DEFAULT_USER=ponponon
      - RABBITMQ_DEFAULT_PASS=ponponon
    volumes:
      - "./volumes:/var/lib/rabbitmq"
      - "./rabbitmq.conf:/etc/rabbitmq/rabbitmq.conf"
    ports:
      - "5672:5672"
      - "15672:15672"
      - "15692:15692"

有人和我一样升级 rabbitmq 版本遇到频繁断联的问题吗？

不知道是不是全新的 4 改了什么特性
