当我运行网关时，我在注册表服务上收到此错误。

2018-07-31 11:23:33.472 ERROR 1617 --- [get_localhost-3] c.n.e.cluster.ReplicationTaskProcessor   : It seems to be 
a socket read timeout exception, it will retry later. if it continues to happen and some eureka node occupied all the cpu time, you should set property 'eureka.server.peer-node-read-timeout-ms' to a bigger value

我使用从发布页面下载的预打包战争文件。版本 4.0.0

有趣的是，当我运行微服务时，我没有收到此错误。它只发生在网关上。

此外，在创建新网关并运行它时，也不会出现异常。它发生在 1 天后，如果你有这个异常，你每次都会得到这个......

使用默认配置我得到了同样的错误。解决方案在于错误消息本身，即增加peer-node-read-timeout-ms值（默认值为 200）。

去你的application.yml

server:
        # see discussion about enable-self-preservation:
        # https://github.com/jhipster/generator-jhipster/issues/3654
        enable-self-preservation: false
        peer-node-read-timeout-ms: 5000
