Processing error: In Block DeepRaw2RGB@node_557[0].Execute

  • Platform: MacOS Tahoe 26.3.1

  • Hardware: Mac Mini M4, 16 GiB RAM, 6 Efficiency cores, 4 Performance cores

  • DxO version: PhotoLab Elite 8.13.0 build 59

  • Dxo settings that might be relevant: maximum number of simultaneous images processed: 8

  • RAW files: ARW shot with Sony Alpha A7RM2, about 42 MiB size

When does this happen?

Most of the time this happens when I export the whole set of 57 images.

How many files are affected?

I repeated the export of the entire set a few times and the number of failed files with this error varied between 1 and 4

Workarounds?

I can export the files one by one successfully.

Ideas on the root case?

I suspect that some weird multi-processing bug is triggered by exporting a large number of files.

What I haven’t tried yet but planning to:

reduce DxO max parallel processing from 8 to 4, will report back in a comment.

So what’s the question?

Has anyone seen this behaviour? If yes, what are the workarounds or tuning actions that proved more effective?

Example of the error window after an export of about 40 images out of which 4 errored:

  • Update:

    I reduced the max simultaneous images from 8 to 4, re-exported all 57 and got 1 error

  • The errored images are always different, albeit some files do error repeatedly
