iOS 9.2.1 app crash on launch

Question

My app works fine in all the versions except iOS 9.2.1

When I run the app on device directly from Xcode I am not experiencing the problem in iOS 9.2.1

Clarification:

I guess iOS kills my app because its consuming more memory and the app is signed by ad-hoc or distribution certificate. when running from xcode I am not facing the problem because its signed by developer certificate and so iOS not kills the app and lets it run

Here is the device log that I got from xcode devices while launching the app
