So clearly the problem that I had lies with some file size limitation with the v.select 'disjoint' algorithm - also failing with one input file prior using the v.extract algorithm. The original (large) input files input to grass ok using v.in.ogr,

The vector limit is as follows:

--> In all GRASS versions, the limit with topology is at time 2^31 - 1
(about 2 billion) features per vector map.

This said, perhaps v.select lacks a proper declaration?

Could you tell us how many vector features per map you are dealing
with (say: those which work and those which fail)?

Best wishes, Markus
