This has been running for over four days mining Monero (cpuminer-multi) on three cores - earlier versions of DietPi and Armbian would crash after one or two days of doing this. Not that I am expecting to make more than 1c a week from this, it is more of a system stress test than anything
I limited my Orange Pi PC down to 912mhz (prevents the voltage kickup on the processor from what I read) on all cores to run my nextcloud…even with 100% useage and running hard updating database and generating thumbnails, it is completely stable…
