Are you supporting the Low Voltage Interrupts in your code?
Is your application moving into a safe mode (not using the PLL) when
these interrupts fire? If you experience a brown out or slow shut-off
but continue to operate the core at full speed then the application
can go off into the weeds and accidentally erase stuff in flash.
