[GRASS-user] v.rast.stats error: "Unable to seek"

[Luí­s Moreira de Sousa]

Hi Stefan, thank you for the reply.

The outputs you request are below. v.rast.stats takes about 8 GB of RAM before failing, only 1/4 of what is available in the workstation. I also tried increasing the memory parameter but it never goes above 8 GB and fails all the same.

Let me know if there is something else I can check. Thank you.
