"loading kernel from nand" - how not sleep well at night

Dear all,

within a month there were three events that caused the network block of a client of mine.
In the network there are 8 CRS125 and 20 RB951G which randomly stopped working.
The error is “loading kernel from nand”. I solved the problem using Netinstall to reinstall the operating system and the configuration of each device.

I never had such problems so far and I am very embarrassed with the customer and I’m worried that the problem will recur again.

According to your experience, what can generate the nand corruption?
I believe may be electrical power surges: in this case, an ups may improve the situation?

Best regards,
Alberto
