Why is tagged as a regression? You does not observe this leak in previous releases like 2.18?

in 2.18 it not works properly with the same file
in previous version of QGIS 3 (but with only 16GB of ram) it worked fine (ram usage about 6-7GB)

same input file and parameters?

Input file is huge but I can provide it Tomorrow,
For settings in geometry checker how should I can share them?
With a screenshot?

Let me know how i can share settings

that was not my question: I asked if the difference in RAM usage amount was noticed using the very same input and configurations in the two QGIS versions you describe.

The dataset is anyway useful, thanks.

Ok the settings in Italian language are in screenshots attached

Thanks a lot

Yes dataset is the same in previous and current version (qgis3)
for qgis2 when i launch the check qgis it crashes and it shut down

Parameters are also the same

#11 Updated by Antonio Viscomi almost 2 years ago

Today I've retry to perform geometry check with the same parameter and the same data
but with a clean user profile

well: the RAM usage was back to normal at about 6.7GB then I suppose that my old corrupt profile caused abnormal usage

than this ticket could be closed

thanks a lot for your attention
