问题是什么:
一个使用 go16 构建的流水线项目，之前(一个月前)还能正常打包成功，今天再次运行流水线时，却无法构建，一直在「环境准备中」，没有报错日志，等了最长有一个小时，也卡在等待 agent 启动：
做了哪些排查：
检索了互联网和论坛，没有类似的案例。
检查了 devops-system 命名空间下的几个 pod 的日志，devops-controller 中与此条流水线相关日志如下：

"runID"="1" 是因为我重新创建了一个一样的流水线进行排查。
进入了 jenkins web 页面，只有一个 Build Queue 的等待状态：
在 devops-worker 的命名空间，也确实看不到相关 pod 被拉起：
（上图这几个 pod ，为了加速流水线构建时间而做了 idleminutes 参数的变更，所以一直持久化运行）
有一个异常的情况是，devops-jenkins 这个工作负载在14天前发生过 pod 的自动重建，在这14天内的其它构建任务中只使用了持久化的构建环境：
请教下，我该从何处继续排查处理此问题？有没有重启 devops 系统的操作？
