MSP430F5419A: Flash self reprogram code suddenly fails after working for 5 years

Part Number: MSP430F5419A


we are a large customer of msp430 devices, we use ~1000s per year.
we have some self reprogramming code that has been working since 2012. 
but lately the code is failing - we can erase the flash but writing fails.
unfortunately the failure means we brick the unit - until someone can JTAG new code into the device!
so, it is strange that we have this reprogramming code working for so long then it starts to fail ... is there any MSP430 issues i should be aware of that might influence this?
