Issues with parallel processing in Drone2Map

I'm running Drone2Map on a new machine (HP Z8 Fury Tower G5) with 64 cores (no CUDA) and running into issues with parallel processing.

I'm trying to generate True Orthos for a set of 1,751 images, and the AddRastersToMosaicDataset tool is consistently throwing ERROR 160281: A requested row object could not be located. The log output reveals two further errors:

  • Error: 8004819c: Could not initialize the mosaic dataset's parallel processing engine.
  • Error: 80048178: Cannot synchronize mosaic dataset items associated with the specified raster type instance. [Name: UAV/UAS; Instance ID: 1]

Since the issue seems to be with parallel processing, I've tried reducing the number of CPU threads (I've tried various numbers between 1 and 105). I continue to get the same errors.

I notice in the log that even when I reduce the number of threads (in both project settings and in the global settings), the AddRastersToMosaicDataset tool doesn't seem to honor that number and always reverts to a parallel processing factor of 50%, which on this machine is 64 threads.

I'm surprised that I haven't seen previous threads on this issue. Any suggestions would be appreciated!
