推荐答案

您的应用程序池可能正在回收.

Your application pool is probably recycling.

您应该在 application_start 中填充任何这样的全局变量，这样即使池回收，它们也会在后续请求中重新加载.

You should be populating any globals like this in application_start, that way they will be reloaded on subsequent requests, even if the pool recycles.

默认情况下，如果几分钟内没有活动，它将被卸载，导致必须从头开始重新加载应用程序.您可以通过在 IIS 管理中配置应用程序池设置来防止或减少应用程序池回收的发生.

By default if there is no activity for a few minutes it will be unloaded, causing the application to have to be reloaded from scratch. You can prevent or reduce the occurances of the application pool recycling by configuring the application pool settings in IIS Administration.
