Question

我有一个jenkins主服务器。我刚刚创建了一个新的jenkins代理，并通过Java Web Start在ubuntu主机中启动它。代理连接成功，但过了一段时间后它会显示＆＃34;终止＆＃34;，然后在一段时间之后再说它＆＃34;已连接＆＃34;。并且它始终如此重复。

我甚至没有尝试运行构建/作业

有趣的是，这个ubuntu代理和这个jnlp以及这个java web start在过去几周一直运行良好 - 甚至直到几个小时前。现在它突然开始断断续续并重复连接，就像这样。

检查jenkins slave日志中是否存在可能的问题。另外，Jenkins节点配置页面下的可用性设置如何？

詹金斯＆gt;＆gt;管理Jenkins＆gt;＆gt;管理节点＆gt;＆gt;您的节点＆gt;＆gt;配置

我最近有一个具有相同症状的Windows奴隶，并从

更改了可用性

＆＃34;在需要时将此代理联机，在闲置时使其脱机＆＃34;

到

＆＃34;尽可能保持此代理在线状态＆＃34;

它解决了我的问题，但你可能遇到了与我的问题不同的问题。所以我建议先查看从属日志。如果可以，请在此处发布日志片段以供进一步分析。

Jenkins代理不断重复断开/重新连接
