No, I did not set any extra parameters except --disable-cpu
I left rigs without restarting miners for more than 24h, and on some rigs hashrate got back where it was(at the same time, on two different internet providers), and on other rigs where hashrate was normal, on those rigs hashrate got lower at the same time as on rigs where hashrate went up(also some rigs are on one ISP, some on other)
