现在只能暂时把健康检查的时间调到50秒

The report names no repository files, tests, or application entry point; it only provides a Java/Netty stack trace and links describing the cause. Start by locating the server handler for port 8070 and reproduce the load-balancer health check, then establish the intended handling and a regression test before changing behavior.
