Hi,
SQLite is known to have problems with network disks (NFS) but that is not your
case. But maybe WSL can have same kind of problems, at least there has been
some https://github.com/microsoft/WSL/issues/2395.
I would try to run the program on true Linux or true Windows and see if the
issue happens to go away.

Thanks for the response,
I've had this issue also with Shapefiles, but haven't tested the other formats
you mentioned. I am not sure what you mean by what kind of file system I'm
using, my program is being run on Windows Subsystem for Linux. I'm not familiar
with journal mode or pragma synchronous, so it's most likely the default option.

Hi,
I believe that the i/o error is something that comes from SQLite. Does error
happen if you save into other formats like shapefile flatgeobuf, or parquet? In
what kind of file system the new geopackage is? What journal mode do you use?
Is “pragma synchronous” on or off?

Aihe: [gdal-dev] GDALPolygonize fails with "failed to execute insert : disk I/O
error"
I'm attempting to polygonize a GeoTIFF using the built-in GDALPolygonize, but
sometimes it fails to write to file. I'm not attempting any sort of
multi-threaded functionality so everything is running synchronously. Here is
the code I'm using to polygonize:
