ASP.NET Core 5，IIS 应用程序池随机崩溃并停止响应

Question

当我的用户超过 20 个时，我在 Windows Server 2008 R2 的 IIS 7.5 上运行的 ASP.NET Core 5.0 出现一些错误。 由于刷新应用程序随机崩溃并留下 503 服务不可用响应。

警告示例：

   dumpproc version 1.249.198.20220919-114646, installer version 1.249.198.20220919-114646

Exception 0xc00000fd: A new guard page for the stack cannot be created.

另一个警告示例：

我真的需要一些帮助来找出这些崩溃的根源。

只需升级您的项目框架，我遇到了同样的问题，并将 .net5 升级到 .net6 然后所有问题都解决了:)
