How much memory do your nodes have?
At present, our CPU’s each have 32 to 96 Gigabytes of memory available to use. Jobs are initially scheduled on nodes with 96GB of memory until one or more frames/tiles completes. Our scheduler notes how much memory was used during the entire run, and will allow nodes with less memory to render frames/tiles if they have more memory than required for the job. Hence, any scene file that requires ~96GB of memory or less should not encounter out-of-memory errors when rendering on Pixel Plow.
