Not sure whether it is pool or miner or pool/miner fault.
The miner continues to work as long as the connection to the pool is alive, otherwise the devfee will be stopped, and the miner will try to restore connection with the pool. I'll connect my rig to Zergpool to see the situation.
I made crutches to restart miner every hour but it's not real solution.
The miner worked for many hours, and i see no problems. Do you see accepted shares? If yes, then there are no problems with the miner, because the pool sends work and accepts shares.
Edit: I'm getting close to a 10% increase in Sol/s with v0.6 and 1080TI
No, there are no significant changes, except one memory fix, which can provide an improvement for 1080ti.
If it will be implemented, it will be later. Just use a stratum proxy for your coin.
