Supernova:
Failed payments are now recredited to your account so you can withdraw again !
Hmm, at same time. Like a entire ZCash network problem, we all need next version of zcashd.
Yes something weird happening today.... the miners I have on your pool with your software is overall stable and steady.
A few miners I have on another pool have been hanging and losing power and shares rapidly. Constantly rebooting those.
Just waiting for you to put the new silent kernel into your miner and all my rigs will be back on this pool
