tytanick,
Have you made any changes to miners/SMOS in last 24 hours? I have started to get reboots on one of my rigs and these huge hashrate swings which I did not have before. My hashrate is 9500 sol/s, but on pool now it swings like mad. My average hashare on pool also has dropped as you can see.

My rigs started tro be very unstable in the last 6 hours
every rig restart every very 1 hour or 30 mins
