Calibration file suddenly empty #26

Closed biesbjerg closed 6 years ago

After rebooting a bunch of times, related to rig maintenance, minotaur suddenly wouldn't start mining.

A calibration file was suddenly empty (my guess is the one that was mining while rebooting).

Maybe a race condition is possible somewhere, where dynamic adjusted hashrates is not always written to file in case of server reboots etc?

i haven't been able to find an explanation for this in the code
