How close client connection to server

[F.D.]

Hi Igniters,

when in my c++ client I close the connection to the server, after a
computation, I got this error:

[11:29:51,542][SEVERE][grid-nio-worker-tcp-comm-1-#34][TcpCommunicationSpi]
Failed to process selector key

To close the client I use this statment:
      Ignition::StopAll(true);

Is it possibile to avoid this error?

Thanks,
  F.D.
