Client not connected

We get an occasional problem when closing a stream.

Message=Client not connected. ->

The apps in question are using SSH.NET 2016.1.0 (net46).

This seems to be the most recent version on the nuget site.

Comienza con el stack trace reportado a través de SftpClient.ReadLines, SftpFileStream.Dispose, SftpSession.RequestClose y Session.SendMessage. Reproduce el cierre de un stream después de ReadAllLines o ReadLines y, a continuación, rastrea la desconexión intermitente; se considera terminado cuando la ruta de cierre ya no informa de "Client not connected" en el escenario reportado.
