我有两个使用RabbitMQ通过RPC通信的nameko服务。在本地使用docker-compose一切正常。然后我将所有内容部署到DigitalOcean上的Kubernetes/Istio集群中，并开始出现以下错误。它每隔10/20/60分钟重复一次。服务之间的通信正常（我想是在重新连接之前和之后），但日志混乱，出现了不应该发生的意外重新连接。
Helm RabbitMQ配置文件
我尝试增加RAM和CPU配置（值为上述配置文件中的512MB和400m），但仍然有相同的行为。
注意：我在部署后没有触摸服务，没有发送任何消息或进行任何请求，而且我在大约60分钟内第一次遇到这个错误。当我进行请求时，它们成功了，但最终我们仍然会在日志中看到这些错误。
