I'm rendering (2.78a + Cycles) a rather complex architectural animation on 3xGPU and just randomly, after any number of frames rendered, Blender crashes. So it does start rendering, goes on for a few frames, and then crashes.
I did what people have suggested in the past (full screen and lock interface), it worked for a while, but not anymore.
Can anyone help? Thank you.
My system is pretty good: i7 6850, 64gb ram, 3x GTX1080 8gb ram. Scene Peak memory at rendertime: 3.4gb (CPU rendering is not a feasible option.)
