停止锁定的按需/触发的 Azure Web 作业

Question

我在Azure中有一个“已触发”的Web作业，它停留在“正在运行”状态，它已经处于这种状态两天了，它计划每5分钟运行一次。

该 Webjob 之前运行没有任何问题。这个问题似乎发生在星期六（我的时区），这意味着它坏掉时没有人在玩它。

到目前为止我已经尝试过：

1. 重新启动 Webjob 所附加的站点。
2. 从 Azure 门户手动运行作业*
3. 重新部署站点
4. 在应用程序设置中设置 WEBJOBS_STOPPED=1
5. 将计划时间从 5 分钟更改为 6 分钟

*这给了我一个错误：

Could not run job: 'EnrolmentProcessor'.
Please try again. If the problem persists, contact support.

所有这些都没有影响进程，它仍然停留在“运行”状态。

我查看了 KUDU 调试控制台中的文件夹，并注意到以下内容：

失败的进程有以下日志行：

[04/15/2016 22:20:02 > 1e4ce4: SYS INFO] Status changed to Initializing
[04/15/2016 22:20:02 > 1e4ce4: SYS INFO] Run script 'TERACC.WebJob.EnrolmentProcessor.exe' with script host - 'WindowsScriptHost'
[04/15/2016 22:20:02 > 1e4ce4: SYS INFO] Status changed to Running

上一个成功的进程有以下日志行：

[04/15/2016 22:15:01 > 1e4ce4: SYS INFO] Status changed to Initializing
[04/15/2016 22:15:01 > 1e4ce4: SYS INFO] Run script 'TERACC.WebJob.EnrolmentProcessor.exe' with script host - 'WindowsScriptHost'

[04/15/2016 22:18:51 > 1e4ce4: SYS INFO] Status changed to Success

有一个名为triggeredJob.lock的文件，在失败时有以下StackTrace：

这向我表明，在尝试处理 Web 作业时出现了问题，导致其处于损坏状态。

我并不担心在“运行”的过程中丢失数据，我只需要让Webjob再次正常运行即可。我该怎么做才能中止卡住的那个并让它重新启动？

Answer 1

看来已经陷入了不好的境地了。我认为关键是删除该triggeredJob.lock文件。问题是它已被锁定并且不想被删除。

请尝试以下步骤查看是否允许删除：

• 使用这些特殊步骤停止站点和 SCM 站点
• 使用 FTP 连接并删除锁定文件
• 重新启动站点（例如从门户）

如果这不起作用，我们会尝试其他方法。我想了解根本原因，但让我们先尝试让您运行。
