If you find problems with an existing product on a recently seeded OS, your first step should be to file a bug about that. And please post your bug number, just for the record.

Having said that, I recommend that you stop using GCDAsyncSocket and switch to Network framework. The technologies underlying GCDAsyncSocket are either deprecated (CFSocketStream) or present solely for compatibility purposes (BSD Sockets).

Share and Enjoy

We re-implemented GCDAsyncSocket using Network.framework to solve this issue. This seamless replacement has been thoroughly validated across a wide range of TCP networking scenarios.
