我有一个 Jenkins 管道由 3 个阶段组成。它包含在不同代理中运行的多个正在进行的构建。代理通过 SSH 启动。我随机面临一些构建中止并显示以下消息。
remote file operation failed: /home/jenkins/workspace/WORKSPACE@3 at hudson.remoting.Channel@759ed7a6:: hudson.remoting.ChannelClosedException: Channel "unknown": Remote call on failed. The channel is closing down or has closed down
获取以下错误日志:
Error when executing always post condition:

能不能解决？
任何与此相关的建议都将受到欢迎。
最佳答案
虽然问题是在 - JENKINS-49707 下跟踪的。
为了克服这个问题，请确保连接的代理上有足够的可用空间。
如果您已经进入错误状态，则断开代理节点与 Jenkins UI 的连接，检查代理中的可用空间并再次使用 Jenkins UI 启动它。
这对我有用。
