[GitHub] [dubbo] AlbumenJ commented on issue #10899: dubbo 启动警告 warn [DUBBO] Failed to start NettyClient 'xxx'connect to the server 'yyy' (check == false, ignore and retry later!)

   这个报错是注册中心推送地址后地址不可达的报错(有可用地址,但是地址连接失败)。
   
   这里的 `check` 的作用是避免注册中心直接剔除这个地址(如果注册中心链路上有报错会直接剔除),日志中的报错在生产定位原因的时候是必要的。即使是没有通过地址剔除这种严格的处理也不应该任何日志不留存,否则在调用出现不通或者报错的时候会给分析带来难度(是注册中心问题还是网络问题还是使用方式问题等等)。
   
   从规范上来说,注册中心是不应该推送不可达地址的,根本应该解决的问题是应该保证下游服务都启动完毕。
