Partially solved in 11.2

Claymore, stability problem!

Almost once a day on different pools, different hardware located on different farms some miner instances suddenly stops at the same time (when on same pool) and blocks batch file from further execution: https://i.imgur.com/leifBzr.png

- i use one miner per card, but even on 1-card farm it may stop
- miner versions are 10.2 and 11
- stops only some of miners but not all, one miner with same card and same settings may stop while other works
- typical period between stops is 12-18h
- rig uptime is not likely to be related
- h values are fine-tuned for each card for better performance, but are 16-fold (h%16==0)
