Asp.net mvc ASP.NET MVC信号器重新连接并协商引发System.OutOfMemoryException

我有一个ASP.NET MVC应用程序正在处理Web Garden配置。应用程序池标识设置为自定义域帐户（具有本地管理员权限）。应用程序池有4个工作进程。会话状态模式使用在同一台机器（而不是远程机器）上运行的ASP.NET状态服务设置为serverState

关于signalr，在尝试重新连接和协商时，我注意到事件日志中存在OutOfMemoryException，我无法检测到发生了什么。我们将非常感谢您的帮助

下面错误中的一些文本是西班牙语（对不起）

下面是重新连接错误：

您可以使用调试诊断工具捕获在IIS中运行的应用程序的数据，在捕获后生成dmp文件，并使用调试诊断分析来分析文件。然后找到outofmemory的原因。@BruceZhang您能提供下载调试诊断工具的链接吗？我担心使用此工具，因为我需要在生产环境中进行调试，我不知道此工具是否会消耗大量服务器资源（从而影响我的ASP.NET MVC应用程序的性能和响应能力）。您可以从以下链接下载：。它不会消耗大量资源。
