High Load Average on HiveOS waiting for NiceHash Algo pool API call
Putting this sequence of events here, as an observation. Not sure about the true root cause but perhaps due to run-away API connection time-out issue ....

Tail end of previous log file:. Notice GAP of 6 minutes "dead zone", between NiceHash Algo Pool API check, and SWARM Warning message:. Then High Load Average ( LA>44) event appeared on HiveOS dashboard, and rig reboot between 01:42:50 and 01:44:24..

If it happens again, zip your .\debug and .\logs folder to me, and I'll investigate.
I'm thinking it's more a miner crashed and that caused the issue on the SWARM side.
