AM's whole point is to try to keep your rigs doing what they do best... mining. You can get really complex with your automation, or keep it simple. That part is up to you.
If your mining software stalls or crashes, your should troubleshoot why that is happening. Maybe the mining software is buggy, you might have driver issues, a bad riser, or power supply issues? Trying to force AM to compensate for these problems will always have you going down a rabbit hole of trying to resolve edge cases.
Right, but if I'm away for some time I also want it to keep mining until I'm able to troubleshoot, hence the question. Good point about changing pools rule, I need to look into that further.
