What's the best way to gracefully close the server?

[miapuffia]

server.Close() gives me errors, as does server.Dispose(). The only thing that seems to work is closing the program. Am I missing something?

I can post more information if that was supposed to work.

server.Stop();

Unfortunatelly this message pops up

I am unable to duplicate this using the latest release (5.0.0-rc.9). If you are still experiencing this issue, can you provide the minimum amount of sample code required to duplicate it so that I can look into it further?
