#494: break in importing and cleaning very large vector datasets ---------------------+------------------------------------------------------ Reporter: gisboa | Owner: [email protected] Type: defect | Status: new Priority: major | Milestone: 6.4.0 Component: Vector | Version: 6.4.0 RCs Resolution: | Keywords: vector import clean build Platform: All | Cpu: All ---------------------+------------------------------------------------------ Comment (by mmetz):
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. ... > Tool: Break polygons > ERROR: G_realloc: unable to allocate 34400040 bytes at break_polygons.c:188 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. -- Ticket URL: <http://trac.osgeo.org/grass/ticket/494#comment:2> GRASS GIS <http://grass.osgeo.org>
