Today I had strange problem with 2.2b version (just updated to 2.3 for tests now)

17547:22:37:32.117: unkn Eth: Connection attempt aborted

Then it switched to 2 other failovers but they could not connect to any.
I had to close program and start it again. There were no connection/network problems. Tried ping and that worked, other rigs were working without problems.

Any hints on it ?



Is there any option like -minspeed ?

Other bug:
Using blockchain drivers, having these results with 2.3:
17547:23:08:20.300: main GPU1: 48C 90%, GPU2: N/A, GPU3: N/A, GPU4: N/A, GPU5: N/A, GPU6: N/A, GPU7: N/A

No difference over 2.2b with fan/temp reporting.



* Found a reason of disconnect. Miner doesn't reconnect when connection is reset without any confirmation from remote side.
