Question

我的GAE应用程序托管在tickets-waiter.appspot.com。它工作得很好，直到一段时间。现在它在2小时内调用/_ah/warmup次请求超过10次。

GAE始终创建我的应用程序的新实例。谁能解释为什么会这样？

以下是一些显示请求和延迟的图表。

Requests and latency graphs

我在appengine-web.xml中的缩放选项：

<automatic-scaling>
    <min-idle-instances>5</min-idle-instances>
    <max-idle-instances>automatic</max-idle-instances>
    <min-pending-latency>automatic</min-pending-latency>
    <max-pending-latency>30ms</max-pending-latency>
    <max-concurrent-requests>50</max-concurrent-requests>
</automatic-scaling>

感谢您的帮助！
