My Ipad 'shut downed' three times in 6month period - HELP-

Had couple of Panic_full, mediaserved, stack-media served logs under Analytics and the dates to the logs were not so close together. It all started When I tap on Ipad, and the screen didnt wake up so I realized Ipad was shut down by itself. I had to plug in the charger to restart and the battery remaining was the same as it was when ON. Another issue was, the Ipad shut down(going black) when plugging in the charger and had to domthe same thing to restart. Battery was not issue.

Visited the Genius bar and they ran test on my Ipad, eventually they found no soft/hardware issues and suggested reinstallation of IOS. Genius bar guy pointed out that I had 3 panic_fulls in the last 6 months.

As I am not sure what logs causing issues were containing at the time of crash, I was able to store one of the panic_full report before factory reset.

Please shed some light and share your story if you had same issues or somewhat in similar context before.

Below is the panic full report (one of them)
