几分钟后 OnD​​emand WebJob 失败

Question

我刚刚创建了简单的 Web 作业，它只是向控制台写入一些内容。这项工作应该按需 运行，所以当我将它发布到 Azure 时，我将其按需设置为 运行。

当我 运行 它时，它工作正常，但几分钟后它失败并显示以下消息。

[12/07/2015 18:07:20 > f78915: ERR ] Command 'cmd /c TestJob.exe' was aborted due to no output nor CPU activity for 121 seconds. You can increase the SCM_COMMAND_IDLE_TIMEOUT app setting (or WEBJOBS_IDLE_TIMEOUT if this is a WebJob) if needed. cmd /c TestJob.exe [12/07/2015 18:07:20 > f78915: SYS INFO] Status changed to Failed

以下是该错误之后的内容：

这是此 Web 作业的完整代码。

static void Main()
        {
            var host = new JobHost();
            Console.Out.WriteLine("Testing the test job...");
            host.RunAndBlock();
        }

我知道它失败是因为没有 activity 但它应该是 运行 按需提供的工作。我哪里出错了？

这是一个按需运行的作业，与错误无关。这只是一项工作，当您告诉它时它就会开始。

在一段时间内（根据您得到的 121 秒）不执行任何操作的作业将中止。
