spring-cloud - Spring Cloud : Zuul Broken Pipe Error

Question

我正在对由 zuul 代理服务支持的简单 Spring Cloud 应用程序进行一些压力测试
由于 Zuul 和服务之间的连接陈旧，我们偶尔会出现管道损坏异常。
我用不同的配置选项配置了 Zuul，但没有成功:

hystrix:
  command:
    default:
      execution:
        isolation:
          strategy: THREAD
          thread:
            timeoutInMilliseconds: 61000


ribbon:
  ReadTimeout: 60000
  ConnectTimeout: 6000

zuul:
  host:
    socket-timeout-millis: 60000
    connect-timeout-millis: 60000

在此先感谢您提供解决此问题的任何线索。
异常(exception)情况如下:
`

我遇到了同样的问题:我通过将 zuul 执行超时添加到 zuul 服务器的 application.yml 来解决它:

# Increase the Hystrix timeout to 60s (globally)
hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 60000
