Microsoft BOT 框架 BOT 间歇性地停止工作

Question

I am facing intermittent issue in BOT.

I have two bots which are written using c# and BOT Framework V4 and both are same and are hosted on IIS.

Also i have hosted two WebChat Node.js applications and both are same.

I have two different Azure registration for two bots.

One bot is constantly throwing issue and it stops working intermittently. Then we have to recycle its application pool to make it start again.

Server : Windows Server 2012 R2 IIS : 8.5.9600

The error is given below,

fail: EnterpriseTestBot.Startup[0]
