Memoty Leak C4dtoa OIDN

Hi, I have had a lot of crashing the last couple of days with 4.0.0.2. It uses all my memory 64 GB, rendering a simple scene, and I'm using the new noise reduction OIDN.

Got this message in the console: [imager_denoiser_oidn] /_display_driver_/Arnold_Intel_OIDN_denoiser: driver_process_bucket OIDN driver_process_bucket Filter Execute Error=out of memory

Can you provide a complete arnold log with the most detailed verbosity level? It might tell us what is going on.

Hi, I've tried to get more info with loging, but havn't gotten any more usefu info. I can render about 500 frames or so, and then it stops.

The log file will be in the CINEMA 4D console, and in a file (if you enable File logging).

The log will have some stats for GPU memory usage (and CPU memory too).

We have a lot of experience reading log files, so we may get more out of it than you.

Thank you. I just updated to 4.0.1 and sadly the problem still occurs. Here's the lates log: https://www.dropbox.com/s/slenuqmdtvd1w8d/log%2024%2011%202021.zip?dl=0

I've tested a lot of possiblities for where the problem can be located. But I cannot find any solution that solve this.

We didn't have time to fix this in 7.0.0.1. When this high priority bug is fixed, you should see ARNOLD-11852 listed in the release notes.
