Raspberry PI 3 does not find blocks
Apparently, a Raspberry PI 3 no more find any acceptable block since Duniter 1.4. It used to work with 1.3.
The computation is well started, but with a difficulty of 5 zeros and 90% CPU configured it seems not enough to find even just a block per day.
IMO, this is a software issue with Duniter being too much asking to the PI, proof excluded.
