Windows Process Activation Service stops responding automatically.

[Sunil G 3]

When I tried to perform Load Testing my Asp.net MVC application, I test application with 30 concurrent users and Application pool stops automatically due to some Window Process Activation Service failed!! Error :--> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.EndReceive(IAsyncResult asyncResult) at System.Net.Sockets.NetworkStream.EndRead(IAsyncResult asyncResult)

In Event Viewer WAS is giving below erros

2. A process service application pool "xyz" suffered a fatal communication error with Windows Process Activation Service. The data field contains the error number
