Hey guys, thanks for the replies.
There is no mud applied, the texture is directly over the metal corner bead. The main problems are on the outside corners, especially were they are subject to abuse from the kids. There are also problems up high away from any traffic. The other cracking areas are at the interior corners where the wall(s) meet the ceiling. It cracks right in the crease and looks awful.
I have a outside corner section that is bare for about 36", and there are nails along the bead edge every foot or so that have a wide head like a roofing nail. None of the beading appears to have any sort of additional covering other than the texture. When the texture comes off the metal bead it stops right at the bead edge and does not continue into the drywall areas.
If I were to remove the metal beads on the worst corners, what would be the easiest way for me to fix and retexture them/
