[GRASS-user] ERROR: Error reading raster data for row 210 of <cumRAD>

[Dylan Beaudette]

Strange,

I used to get this type of error when running r.series on a large
number of maps, but seemingly at random. I would re-make the map that
"caused' the error, re-run r.series and it would usually work.

Time passed and I forgot about it. I assumed that updating to grass71
(trunk) was the solution.

This afternoon the error returned when using t.rast.series

Error reading raster data for row 292 of <gdd_139>   !!!

Again, these errors seem to happen at random. In this case, I am
iterating over a sequence of years and computing growing degree days
via t.rast.series. Here is the output from several years:

1984

         unregistering all maps

         maps


... the stack of rasters called "gdd" is re-computed for each year.
Everything worked as expected in 1984, read error in 1985, fine again
in 1986. There is no MASK present.

I have only ever encountered these errors when using t.rast.series and
r.series. Does anyone have any ideas on how I can replicate or
otherwise debug these kind of errors? This is a serious problem for
long-running calculations.

Thanks!
Dylan
