I have very specific overlocking with constant voltage and my PSU works on 80% of their power with my overlocking, when Dev's session starts it makes my PSU work on 100% and it crash everything. Why don't you just make dev's sessions in the same algorithm as users session ? It will resolve any issues.

p.s I'll try i 5 but I guess my suggestion will be much better

p.p.s : Same picture with -i 5 https://ibb.co/eac4rd and https://ibb.co/jBqqWd

Please make it finally fixed. Your miner is the best but this thing makes me using ccminer...
