KODI 16.1 reboot my box

Hi you all

Marshmallow 6.0.1 64Bit

I see nothing in log files about this event but KODI reboot my box 2 time this week !

This happens when reading a large HD file. In middle of viewing the movie (streamed from my PC) my box rebooted alone.

I do NOT have any add on.

Any comment welcome
