Code Corrupted after full discharge of batteries, upon reboot. NRF51822 SDK 12.3

Hello Nordic Wizards,

We are in the final throws of a project preparing to go to market.  However we have identified a "strange" problem.

if the batteries driving the board power are allowed to fully discharge, once they start recharging, plugging/unplugging the board from a charger resets the board and may lock the code up in an unknown state.  If the board is reprogrammed, this condition stops, until the next time the battery/board is fully discharged.  Has anyone see these types of problems with this chip, and/or can you point me to a prospective solution.

Thank you kindly
