all others  have similar  symptoms right now
15 min  in total  lost somewhere as pool not get info from miners, near all miners got same time +/-5 min interval as all booted same time
now  is back to live ,so dont know reason, log show  identical problem every more or less 4-5 hours range now after restart  all logs gone of curse
