Manual restarting for me wasn't even an option, I've lost sooo much hours due to vertminer or connection errors
I have had it stop working when I went to work before and cgwatcher can't restart it. When I came back from work, it lost a few hours mining
But even without cgwatcher, my miners have trouble reconnecting to failover pools some of the times. it just stops working and I manual restart
Not quite sure where the problem is really
