i've been on your pool for about 6 months, but the last week or so when i get home I notice my workers are at 0 MH/s. when I restart them, they go back to their usual rate, then in a few hours they stop getting blocks again and go back to zero, so I have to keep manually restarting them in order for them to continue mining.

I tried api and api2 urls and it has made no difference. is anyone else experiencing this issue?
