It's not a crash report, but I do experienced crash as a user (not by crash log), and I fail to catch the crash. I think there must be a crash log from Xcode device log or somewhere else.

I do agree that the log is not a crash report, but I do experienced a crash as a user, and the app process terminate can be corroborated by my app logs. So I think there must be a crash log, I suspect the wakeups cause the crash.
