ASP.NET MVC Signalr重新连接并协商引发System.OutOfMemoryException

如何解决ASP.NET MVC Signalr重新连接并协商引发System.OutOfMemoryException

我有一个在Web Garden配置上工作的ASP.NET MVC应用程序。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。使用在同一台计算机（而非远程计算机）上运行的ASP.NET状态服务，将会话状态模式设置为serverState。

关于信号器，在尝试重新连接和协商时，我在事件日志中注意到OutOfMemoryException，但我无法检测到正在发生的事情。任何帮助将不胜感激。

以下错误中的某些文本是西班牙语（对不起）。

以下是重新连接错误：
