与 OnePerRequestModule 相关的 Ninject 间歇性异常抛出

Question

我刚刚将 Ninject 的现有实现从 1.5 升级到 2.0。我现在看到在短时间内发生许多请求时会抛出间歇性异常。

这是正在抛出的异常。

Type: System.ArgumentException
Message: An item with the same key has already been added.

如果我删除 OnePerRequestModule，则不会抛出异常项目来自 httpModules在 web.config 中，但这会增加大量开销。

如果他们能提供帮助，我提前感谢任何人!

存在多线程问题。尝试使用在 https://github.com/ninject 中找到的 2.2 RC1 .请告诉我此版本是否仍然存在此问题，以确保我们在发布之前没有需要解决的其他问题。
