[GRASS-dev] r.to.rast3 error messages

Hi devs,

When running r.to.rast3 with as input two integer maps:

r.to.rast3 input=soc_0_5cm_mean,soc_5_15cm_mean output=test

I am getting the following two warnings:

WARNING: G__open_misc(read): Unable to open ‘/home/paulo/grassdb/Schijndel/soils/cell_misc/soc_5_15cm_mean/nullcmpr’: Too many open files
WARNING: G__open(read): Unable to open ‘/home/paulo/grassdb/Schijndel/soils/cellhd/soc_5_15cm_mean’: Too many open files

and the error message:

ERROR: Error reading reclass file for raster map soc_5_15cm_mean@soils

I am really not sure what these messages are about. The warning messages do not seem to make sense, I am only using two files as input. I do not understand the error message either, or what the reclass is referring to.

Any idea, is this a bug I should report, or something I am doing wrong?

Mvg.

Paulo

Any chance you are running something else at the same time? Generally, there is a limit on the number of open files (see e.g. r.series man page).

I thought of that, but the same error occurred after running the function as first thing after restarting grass gis.

It could be influenced by other processes apart from GRASS, the limit is not per program but per user (I think). Sorry, no better idea here.
