I used to get outages all the time. Everytime I came home from fiat mining, I needed to restart the thing.
After I updated to v2.1.10, first impression was "damnit the high temp. stopped it again and again".
But that was not the case. The heatwave we had was so unbearable, even #bitaxe had enough of everything :)
Well the workaround in high temperature environment was to lowering the **core voltage** and a **frequency**
After this setup It's running smoothly for 6 days already without any hiccups
