此实例的状态已从外部设置为无服用毒丸

如何解决此实例的状态已从外部设置为无服用毒丸

我们在 kubernetes 上运行气流。虽然气流运行 DAG 没有任何问题，但我在气流日志中看到以下奇怪的错误消息。

但是，当我查看运行 DAG 的 kubernetes pod 日志时，它没有任何问题，并且 DAG 中的所有任务都已成功完成。我在气流日志中收到以下错误消息的任何原因？此外，所有日志都没有打印在气流日志中，尽管所有内容都在 kubernetes pod 日志中打印而没有任何错误消息。

气流日志正在打印消息，直到 python 代码中的一个步骤花费超过 1 小时......这就是气流日志停止写入文件的时间。不确定这是否与运行超过特定时间时的任务超时有关

如果您对此有任何想法，请告诉我。谢谢
