Error: Labeled Maxima

Hi, does anyone know what would be the reason of causing this error?

It only happened when I start the analysis but not when I use test mode…

Can you confirm your OS and your version of CellProfiler? Does it happen in all images, or only some?

Looking at the code I’m struggling to find a scenario where this error could happen. Would you also be able to upload a copy of the pipeline you used?
