我在BOT中面临间歇性问题。
我有两个使用c＃和BOT Framework V4编写的机器人，它们都是相同的，并且都托管在IIS上。
而且我还托管了两个WebChat Node.js应用程序，并且它们都是相同的。
我对两个机器人有两个不同的Azure注册。
[一个机器人不断抛出问题，并且间歇性地停止工作。然后，我们必须回收其应用程序池以使其重新启动。
服务器：Windows Server 2012 R2IIS：8.5.9600
错误在下面给出，

这种特殊问题需要在GitHub（https://github.com/microsoft/botbuilder-dotnet）上提出，因为这将特定于您的机器人。
