I see I'm not alone with this error each time devfee tries to connect to cryptonight.usa.nicehash.com, here are my log files if anyone can help...
Everything seems to be OK at the beginning, then the devfee comes :

15:31:18:730 b9466740 watchdog - fminer thread hangs
15:31:18:730 b9466740 em hbt: 0, fm hbt: 120365,
15:31:18:730 b9466740 Miner thread hangs, need to restart miner!
15:31:18:730 b9466740 GPU 0 temp = 58, old fan speed = 60, new fan speed = 60
So the miner tries to restart and here are the lines that are not in the same state than previous starting :
GPU #0: Ellesmere, 748 MB available, 36 compute units
card 0, m1 748, m2 512 w 288
0 m = 0
Bad performance mode, you need to set GPU_MAX_ALLOC_PERCENT 100
GPU #0 algorithm ASM, -h 900, -dmem 1 (Memory used: 3780MB)
OpenCL error 0 #101 - -61, cannot create GPU memory buffer
OpenCL error 0 #101a - -61, cannot create GPU memory buffer
Here is what I can read for the first start :
GPU #0: Ellesmere, 8055 MB available, 36 compute units
card 0, m1 8055, m2 4048 w 288
0 m = 2
GPU #0 algorithm ASM, -h 1800, -dmem 1 (Memory used: 7560MB)
I tried with overclocked bios, with stock ones, tried to remove -dmem 1, tried with other pools... Still the same error... Last week with exactly the same args, I had no problem... I thonk it's due to devfee mining pool but I'm not sure, I have to use -nofee 1 for the moment but I'd prefer find a solution...
Oups I forgot, I mine electroneum ETN with that card
