iPhone 6 plus crash issue

I've migrated my ARC supported project , after successful migration when I tried to run the application in iPhone 6 plus(8.1.3) , the application crashes & the reason it shows as

alloc: * mach_vm_map(size=16384) failed (error code=3) * error: can't allocate region *** set a breakpoint in malloc_error_break to debug

Kindly help me in this.
