Sounds like a hardware stability issue. My render is going consistent. Can you post a screenshot with PV? I see long scene creation times in your log, about 85 secs. Mine is 5 sec. It's very strange.
Right now, I cant, but I tested something.
I reduced the TdrDelay back to 10 seconds, as I felt ...

take look for render statistics for the frames. Check where they spend time and compare render speed
It seems to be "Start Rendering" which takes more and more time. In this scene I have 15 seconds for the 2nd frame, and 1 minute for the 100th frame, 1:42 150th frame... c4d and Log attached. The ...

OK so share some data with me to show crashes.
Screenshot/_bugreport.zip/console outputs
I will, yet no crashes occur since I changed the delay to 60 seconds. What happens now is that every frames takes longer than the one before, unless I restart the rendering.

Frame 1: 49 Seconds

Frame 949 ...

system has 128gb ram, gpu 10gb.

The scene shows it uses 2.9gb vram and claims 5.7 are available, from second frame on it is 1.7gb free, sill 2.9gb used. Thats odd, no?

After having an issue with a heavy scene, making it crash every 20 frames, more or less, I decided to reinstall my gpu-drivers. Did not help. Now I realise older stable scenes, when rerendering, crash every few frames aswell. The error is "cant unload gpu memory, device x deactivated". So I browsed ...

Hey guys,
since Ive updated my Studio Drivers to version 441.66 Octane crashes during Live Viewer Rendering, in the Render Queue and while Rendering to the Picture Viewer, in my case in Cinema 4D R20 with multiple Geforce 1080 ti cards.

I found some topics in the C4D-Octane-Forums and on Reddit ...

Sure. Yet Maxon Support told me they get a lot of these scenes to fix. So yeah, might be not too uncommon. Especially since it shouldn't be possible to create loops which kinda break the scene.

Hey guys,
once in a while it occurs to me that older Cinema 4D Files with Octane Materials won't open. It loads forever, gets stuck, c4d freezes. Reason for that are Cinema 4D Gradients used inside the shader tree. They are supported, you may use them, but sometimes it can be problematic. It seems ...

Pardon?

Hey guys,
I'm using a linear field to steer clones' opacity via mograph color shader. The Field is animated across the clone array. Works perfectly in Live Viewer, works completely not in Picture Viewer. What am I missing?
