Adapter unable to connect to multiple clients.

[adityarauniyar]

The steps:

1. Adapter is running successfully and gathering data.
2. Agent connects to the adapter and collects data as expected.
3. A telnet to the adapter port rejects any connection.
4. The telnet connects as soon as the agent is stopped.

I think that the additional clients are in a queue till the connected client thread is terminated. Ref

Have tried to test the following code and seems to work. Please review.

private void HeartbeatClient(object client)
        {
            ...
            // Send intial stream to the client
            SendAllTo(clientStream);
            ...
            try
            {
                while (mRunning && tcpClient.Connected)
                {
                   ...
                }
            }
        }

        private void ListenForClients()
        {
            mRunning = true;

            try
            {
                while (mRunning)
                {
                    //create a thread to handle a new communication
                    Thread clientThread = new Thread(new ParameterizedThreadStart(HeartbeatClient));
                    //.AcceptTcpClient() blocks until a client has connected to the adapter
                    // a connection attaches the new client to the new thread
                    clientThread.Start(mListener.AcceptTcpClient());          

                }
            }
            catch (Exception e)
            {
                Console.WriteLine("Execption occurred waiting for connection: " + e.Message);
            }

            finally
            {
                mRunning = false;
                mListener.Stop();
            }
        }
