Autocad file labelling

[BARNES DAVID]

Hi 
   We are trying to label autocad contour lines using the procedure
v.cadlabel. But we are getting the following errors :

 
   Contours:

Attaching Labels to contour map: 
Label 900 ran into label 905, Line 264
Label 900 ran into label 905, Line -281
FAILED to find node for Tline 12
FAILED to find node for Tline 32
Label 875 ran into label 885, Line 16
Node #216: 3 lines intersect here
Node #216: 3 lines intersect here
Node #260: 4 lines intersect here
Node #209: 4 lines intersect here
Node #209: 4 lines intersect here
Node #300: 4 lines intersect here
Node #300: 4 lines intersect here
Label 905 ran into label 900, Line -489
Label 905 ran into label 900, Line -489
FAILED to find node for Tline 68
Label 900 ran into label 905, Line 189
Label 900 ran into label 905, Line 189
Label 890 ran into label 895, Line 108
Label 890 ran into label 895, Line 108
Label 895 ran into label 890, Line 109
Label 895 ran into label 890, Line 109
Label 905 ran into label 910, Line -516
Label 905 ran into label 910, Line -516
Label 910 ran into label 905, Line 89
Label 910 ran into label 905, Line 89

We don't know what are all these errors. 
What does it mean by negative line number.
How do we locate so and so node in the map.
Do we need to edit the map to eliminate these errors. 
If so can we do it in the GRASS or do we need to go to Autocad

Could someone please clarify the doubts.

Thanks, Barnes
