I have a stored procedure with some input parameter and one output parameter.
I use SqlCommand and SqlParameter as following

///Set some imput parameters here

parameter = cmd.CreateParameter();
parameter.ParameterName = "OutputParameter";
parameter.DbType = DbType.String;
parameter.Size = 16;
parameter.Direction = ParameterDirection.Output;
cmd.Parameters.Add(parameter);

cmd.ExecuteNonQuery();


However, the last statement generate the following error and the connection
closed because of that:

A transport-level error has occurred when receiving results from the server.
(provider: TCP Provider, error: 0 - The specified network name is no longer
available.)

Any ideas?
