So, I posted an issue I've been having with Claymore v11, where 2 rigs constantly restarts in 2 hours or less on one rig and on the other I'll be lucky to get 6 hours of uptime when mining ETH forks. I streamlined it down to the second dev fee mining, where the miner repopulates the dag file size on the gpu's even with the allcoin -1 option, put the most critical rig back to mining ETH and it runs 10 to 12 hours before any crash. So, definitely claymore dag issues with ETH forks. I might be still wrong.
