 Replying to [ticket:494 gisboa]:
 > I try to use Grass with large vector files, with sizes up to 0,5GB, this
 usually results in errors during import, or if not during import, then at
 least while cleaning them.

 Cleaning vector files of this size (about 0.5GB) in v.in.ogr or v.clean
 can require a lot of memory, up to 8GB. Is it possible that you ran out of
 memory? Physical memory plus swap space smaller than 8GB? If yes, increase
 physical memory and/or swap space, and try develbranch_6 instead of
 6.4.0RC3.
