#3330: t.rast.to.rast3 error: Argument list too long
----------------------+-------------------------
 Reporter:  richardc  |      Owner:  grass-dev@…
     Type:  defect    |     Status:  new
 Priority:  major     |  Milestone:  7.2.1
Component:  Temporal  |    Version:  7.2.0
 Keywords:            |        CPU:  x86-64
 Platform:  Linux     |
----------------------+-------------------------
 The following error is output from t.rast.to.rast3 when more than 5000
 raster layers in a STRDS and used.


 'AFAICT, the issue is not with the number of open files, but with a list
 of map names (arguments) that is too long for the run_command call that
 calls r.to.rast3. A solution to this could be to allow as input to
 r.to.rast3 a file with map names (such as for r.series).

 You should create a bug report for this.
