Hello,
  
r.to.vect produced after approx. 24 hours the error message "D3/5: new node =
3101610, n_noKilled" (full output see below).

r.info of the input file "vcf_1" gives:

Type of Map: raster
Number of Categories: 253
Data Type: CELL
Rows: 3797
Columns: 6905
Total Cells: 26218285
Projection: Lambert Azimuthal Equal Area (zone 0)
N: 1728000 S: -170500 Res: 500
E: 1634500 W: -1818000 Res: 500
Range of data: min = 0 max = 253

exactly the same file but with just 8 categories works fine.
