#1903: r.watershed fails with "Subprocess failed with exit code 6" -------------------------+-------------------------------------------------- Reporter: marcosc | Owner: grass-dev@… Type: defect | Status: new Priority: normal | Milestone: 6.4.3 Component: Raster | Version: svn-releasebranch64 Keywords: r.watershed | Platform: Linux Cpu: Unspecified | -------------------------+--------------------------------------------------
Comment(by marcosc): LFS is enabled, but we are working on a 64-bit platform anyway. The command: {{{ r.watershed -fm elevation=... accumulation=... drainage=... basin=basins stream=... threshold=10000 memory=25000 --overwrite --verbose }}} ... with: {{{ g.region -p rows: 38728 cols: 55611 cells: 2153702808 }}} ...results in: {{{ ERROR: G_malloc: unable to allocate 596992000 bytes at setup.c:64 WARNING: Subprocess failed with exit code 256 WARNING: category information for [flow_accumulation] in [r.watershed] missing or invalid WARNING: category information for [drainage_direction] in [r.watershed] missing or invalid WARNING: category information for [basins] in [r.watershed] missing or invalid WARNING: category information for [streams] in [r.watershed] missing or invalid Removing raster <MASK> [H[2JClosing monitors ... Cleaning up temporary files ... Done. }}} The system runs with 32 gb of RAM, so ~600 MB shouldn't be a problem. We checked the setup.c in /lib/segment/setup.c but could not locate the problem. -- Ticket URL: <http://trac.osgeo.org/grass/ticket/1903#comment:2> GRASS GIS <http://grass.osgeo.org> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
