Gewusst wie: Debuggen von "watchdog timeout" crash-logs?

Ich bin etwas neu mit iOS crash-logs - ich bin ziemlich vertraut mit app-basierten crash-logs, da Sie ziemlich einfach zu symbolicate, aber ich bin immer noch versuchen, herauszufinden, wie zu Lesen von Protokollen von einem watchdog-timeout. Um klar zu sein, diese timeouts sind verursacht durch ein Notification Center widget, die ich Schreibe, läuft als Teil des SpringBoard-Prozesses. Die Unterbrechungen sind in der Regel verursacht durch einen Fehler in meinem code (dh. der Zugriff auf ein Objekt freigegeben), aber anstelle einer regelmäßigen crash-und crash-log, Sprungbrett einfach hängt für 2 Minuten, bevor der watchdog löst einen respring.

Also ich denke, meine Frage ist zwei-Fach. Erstens, warum ist es, dass SpringBoard ist einfach hängen, wenn mein code etwas falsch macht, lieber als ein Absturz (und daher geben Sie mir eine weitere nützliche crash-log)? Und zweitens, wie kann ich die watchdog-timeout-logs, um herauszufinden, die Quelle der das Problem in meinem code? Ich habe versucht meinen code kompilieren mit der -g Flagge und DEBUG=1 option Satz in meinem makefile (mit theos), und aktivieren syslogd, aber keiner von diesen haben die betroffenen der Ausgang des watchdog-timeout meldet, leider. Vielleicht bin ich auch nur etwas fehlt, aber ich kann nicht herausfinden, wie die Informationen in diesen Protokollen, oder wie man Sie nützlichere Informationen als das, was da ist.

Hier ist ein Beispiel-log von einem watchdog-timeout für die Referenz. Ich habe versucht, nehmen Sie nur die entsprechenden Abschnitte der log, aber ich kann das gesamte log, falls erforderlich.
