Iray Iteration Count Reset Question

I've noticed lately that my Iray renders go for the first 20 iterations, then restart at 1 and proceed normally after that initial cycle. Is there a reason for this?

    The few times i've encountered this, it's usually iray trying to use the gpu then glitching(hitting the vram limit) and switching to cpu.

    It generally cleared if i closed out DS and reloaded the scene.

    In a few cases i've had to rebuild the scene, reloading and copy/pasting poses and so forth, and resave.

    the worst case i had to restart the system.

    Thanks for the reply. I have been rendering heavier scenes, so the VRAM limit theory makes sense.

    To test this theory, deactivate GPU for rendering. And let the scene run only on CPU cores. If this never happens again then yeah, that might be a reason ;)
