We have been witnessing the same thing, but rest assured this doesnt say anything about the code of AtheistCoin or about Sgminer. However, with what we currently know it is most likely a (temporary) bug in the pool (software). The fact that it seems to be solved at suprnova after ocminer restarted makes that even more plausible. We are trying to get more information, but since the 'bug' is not in our code all we can do is try and find out what is wrong. Rest assured that we will do whatever is in the realm of possibilities.
