To all who reported / experience random CUDA failures with error 2: We are working on this issue for quite a while now, and I just wrote a status update about where we are right now:
viewtopic.php?f=24&t=69639
I'm sorry that it isn't solved yet, but pPlease continue sending scenes / steps to reproduce the failure to Ahmet or to me so we can continue trying to fix / work around it.
Thank you,
Marcus
