Who can solve this problem ? I close tool and run again, it's normal
But many rigs are faulty
A couple people above complained about this issue. I myself had these errors a few times. And indeed a soft restart (closing and opening EWBF) fixes it.
I just increased virtual memory from 30 to 50 GB and never had that problem again (4-5 days running stable).
I´ve got the same problem.
I´ve got 75gb on VM.
