Your crash report has this crashing thread backtrace:

Thread 8 name:

which doesn’t match up with the backtrace in your original post. What makes you think that these are related?

If you’ve matched these up based on frames 3 through 0 then that suggests you have memory management problems, that is, you have separate subsystems within your app (NSURLSession and CFNetService) that are crashing when releasing an object. In that case I recommend that you apply the standard memory debugging tools, and especially Zombies, to see if they make the problem more reproducible.
