I’ve seen there are others with this problem, take a look at these previous threads

Judging from this discussions looks like this is related to RB333 only, and to its
specific feature of monitoring the health (voltage) of the routerboard.
Maybe is there something wrong with health monitoring, that’s why it wasn’t
implemented anymore on others RouterBoards?
But what about RB333? Can be introduced an option to disable this option
in case we experience such problems?
Thanks
