Can You elaborate? I didn't receive any complain, so can't help You if I don't know what's wrong?

The only possibility of above situation is when You setup wrong pool or Your pool become dead..This way, cgwatcher will restart rig every 10minutes because TOTAL hashrate (accepted and rejected shares) is equal to 0. After computer restart for short period of time defaults pools are being restored. Then after 1-2min leaserig.net service will point back to Your pools...Then whole process repeats...

I have 400h+ rented hours and yet You come here and accuse me about things I haven't done. Why You don't write to me so I can check things out ?  Be aware that leaserig.net service was moving to dofferent location what caused a lot of problems, even I was not able to manage my own rig for some time.

best regards,
Matt

I believe this is You:

You rented rig for 1 hour and You write such feedback? I was monitoring this case and it happened exactly what I wrote abbove. You have setup pool which was something wrong with it on Your side, thus rig was restarting every 10min due to 0 shares being accepted or rejected.

Thank you
