RabbitMQ .NET Client library Code 541 Unexpected Exception during load testing

Question

Our application uses RabbitMQ .NET client to publish and consume messages and during loading testing we are getting the following issue in one of our application where the connection to RabbitMQ gets dropped. The following is the stacktrace of the application,

Message: Already closed: The AMQP operation was interrupted: AMQP close-reason, initiated by Library, code=541, text='Unexpected Exception', classId=0, methodId=0, cause=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 (10054): An existing connection was forcibly closed by the remote host. at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.IO.BufferedStream.ReadByteSlow() at RabbitMQ.Client.Impl.InboundFrame.ReadFrom(Stream reader, Byte[] frameHeaderBuffer) at RabbitMQ.Client.Framing.Impl.Connection.MainLoopIteration() at RabbitMQ.Client.Framing.Impl.Connection.MainLoop() Type: RabbitMQ.Client.Exceptions.AlreadyClosedException ShutdownReason:

Any idea why this happens?
