If one has problems with Miner/GPU/Worker going down from time to time, one should have the whole process of restoring them automated.
Much easier to do in linux, but can be done in windows too, just easier in linux.
At some point one will have need to manually perform maintenance, even when running Linux. Having separate workers for Computer/GPU, makes targeting that Computer/CPU that much easier.
I don't have to touch my rigs even if there is a hard lock, unless I want to.
Sure, if some hardware fails physically there is not much any automated software can do about it unless you have a robot available.
But such a failure would be displayed in the monitoring logs/graphs as that rig would stop responding or report very odd values.
