在这里寻求帮助！
我正在运行Jenkins（v2.134）作为由Rancher（v1.6.16）管理的Docker容器;我使用haproxy（HA-Proxy版本1.6.3 2015/12/25）作为我的负载均衡器。Jenkins JNLP端口配置为50000。haproxy获取TCP端口转发规则（8081 > 50000）
我的从机（macmini）在不同的网络和防火墙后面（这个网络可以到达我的Jenkins Infra）。我使用的是“Tunnel connection through”属性和指定端口“：8081”。端口8081已在防火墙中打开。
我的Jenkins Java版本是-

openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-1~deb9u1-b12)

我的奴隶Java版本是-

Sun JDK "1.8.0_151"

这是探员日志

我发现了问题;它是与我的负载均衡器（haproxy）默认超时的TCP连接（如果没有流量），这是50000毫秒。https://cbonte.github.io/haproxy-dconv/configuration-1.5.html
然而，Jenkins ping从站（即哈德逊.slaves.ChannelPinger.pingInterval）的间隔为5分钟（dafault）。https://wiki.jenkins.io/display/JENKINS/Features+controlled+by+system+properties
增加负载均衡器超时，即5分钟解决了这个问题。

如果以前使用此选项限制过频繁的重新连接，则还可以从参数中删除-noReconnect。
