I have two S19 and i moved them to my new house.
After moving i started to have this problem. After mining for a while (sometimes 15 minutes, sometimes 10 hours) they suddenly stop hashing (in different times). It shows rate Abnormal. Temps are generally good (around 50 - 75). By the way, i use both of them in a silencer box.
* I tried to use UPS to avoid voltage problems (if any)
* I tried many cooling solutions. I doubt PSU heating problems.
* Network problems ? (but cant see a clue in the log)
Please kindly assist me for this problem. 2 examples of Log will follow in the next posts
