Возникают проблемы с пониманием отчета о сбое без использования связанных методов из моего кода
Похоже, это связано с сетевым потоком, большинство других потоков находятся в состоянии "mach_msg_trap". 4-й поток в списке - тот, который потерпел крах. Я использую AFNetworking на iOS 7.1
Я ценю любую идею или мысль, которая может помочь мне исследовать эту проблему.

Похоже, вам нужно исследовать вызовы этих функций: mach_msg_trap а также semaphore_wait_trap, Это главная причина крушения. Иногда вызовы этих методов на вершине стека являются индикаторами получения тупиковой ситуации. Вот несколько ссылок для расследования:
- IOS semaphore_wait_trap в основном потоке, вызывающий зависание в пользовательском интерфейсе
- http://iphonedevsdk.com/forum/iphone-sdk-development/7354-what-means-mach-msg-trap.html
- Блокировка с помощью AFIncrementalStore и NSFetchedResultsController
Попробуйте воспроизвести сбой, запустив приложение, откройте URL-соединения, отправьте приложение в фоновый режим, подождите несколько секунд, а затем переведите его на передний план.
