[GRASS-dev] Shape import : out of memory

[Otto Dassau]

Hi, 

I try to import a 1GB Shapefile and the geometries seem to be in a really
bad condition. Building topology GRASS exits after 30 hours with an OUT OF
MEMORY! error (see below). 

Can someone give me hint, what I could do, to import this file? Using -c or
-f flag is no option, because I would like to use GRASS to clean the data as far
as possible automatically and I wouldn't like to split the file into subregion,
if I don't have to.

The PC I use is a dual core 1,8MHz with 4GB RAM and 1.6GB swap. Is this still
not enough or can I change something in GRASS (extend or change memory
parameter) to finish the import? I used a svn version from yesterday. 

below you see parts of the 230MB log file:

 thanks
  Otto
