Response resp = client.SayHello(new Request(), deadline: DateTime.UtcNow.AddSeconds(5));
}
catch (Exception e)

// exception will happen because of this is no such server
Console.WriteLine("error=" + e);

{

}
}
}
What did you expect to see?
the client's memory is steady
What did you see instead?
when use grpc 1.8.3, memory increases overtime. but memory use seems steady when when use grpc 1.7.1.
