Exception when connected on Linux

I'm trying to deploy my project based on dotnet core 1.1.1 and DotNetty 0.4.2 to a CentOS 7 machine. Which worked fine when debugging on Windows.

There is an warning every time I connect:

```

```

However things seems to be working, I can see my Console output when I send message from client.

Is this something I should concern about?
