在 IIS7 上从经典迁移到集成后出现警告

Question

我已将我的 c# asp.net Web 应用程序从 .net 3.5 迁移到 .net 4.0，并将其运行的 IIS7 应用程序池更改为集成的而不是经典的。该网站运行良好，但我发现服务器事件日志中记录了以下警告：

任何想法可能导致此问题，因为我对它可能是什么感到困惑？

Answer 1

（技术难度：我无法为您的问题添加评论，但似乎我可以将其添加为答案）

我遇到了同样的错误。在此链接中 https://jira.springsource.org/browse/SPRNET-1456 他们说这是一个“不会被修复”的错误

Answer 2

我遇到了这个错误并查看了事件查看器。在其他几个错误中，我遇到了一个和另一个错误（这是一个信息）：

所以这是一个堆栈溢出。我猜您看到的错误只是另一个错误的产物。您应该尝试调查此其他错误。我并不是说它会像我的那样成为 stackoverflow，但它可能是其他东西。
