I set up my new R-Boxes yesterday and they are running fine... for about 1 hour. Then one miner is being flagged as "Idle for more than 60 seconds, declaring SICK!" and a big red "sick" flag pops up. IF this continues, the flag turns to "dead." This is also intermittent (they have been running for 6 hours today without an issue).

Does anyone know what this error means/what causes it/whether to worry/and how to fix it?

Thanks.
