[GRASSLIST:4370] Import ascii points - Grass5.7

[Michael Cunningham]

Does anyone know if there are memory limitations to memory size of 
importing ascii files?  Example, importing a 300Mb (X, Y, Z) gives a memory 
alloc fault after about 2 hours of running.  Don't think it's machine (dual 
G5, 4Gb Ram OS 10.3, Mac).  I can import files >1Gb  in Grass5.3 (i.e. 
sites).  I've tried importing sites and then converting to new grass5.7 
vector layer, with the same error.  Any help or pointers much appreciated.
