Kyle this is awesome! Good sleuthing!

and by “make sure that your server is accepting streams multiple times” I mean your server should make sure it is accepting multiple open stream events NOT that you need to accept each stream twice.

May I query where you got that log output, I am using CFNETWORK_DIAGNOSTICS=3 on my product scheme, are you attaching via Console.app? It'll help me with my other problem which which I will take to another thread.
