I am writing this to ask regarding the methods to find a bug fast. For this I would like to mention a case which I want to solve from 2-3 months.

We have Our meters based on MK20 series controllers. Meters behave absolutely well. But there is case when sometimes it restarts after every predefined time which may be due to watchdog. But this is very very rare event. 

      One Meter came to me from feild, I tested it for 2 days but this event came only once, after that it didnt came and we returned the meter with fresh firmware. But knowing the problem is unsolved.

     So, I am curious to know that how to solve this issue?? 
   So, it is is my request to guide me with a case study so that it can help me to solve the problem. For eg., Read the .MAP file or some code in DEBUGHAULT may help or some other things which go really deep inside to solve the issue.
