Rim cracks on spoke adjustment holes, how much should I panic? So I have a RODi Rims SKORPION rim and I've noticed that there are cracks on the holes for spoke adjustment. They all appear to be on the left side of the bicycle and I'm not sure if they were here before or not. On some holes, cracks are bigger and on some other holes, they are smaller. Some holes don't have them at all. I'd say that in total, around 90% of the holes have at least some cracks. 

  

Is this a cause for concern or not? The rim is around 11 months old and I think I've passed around 1200 km with this rim.
To me, it looks like whoever (or whatever, as it was likely machine built) used the wrong size tooling to hold and screw the spoke nipples as the wheel was built. Not a rim manufacturing defect but a wheel building defect. 

If it's still under warranty, I'd get the wheel replaced. Any cracks are bad cracks and could propagate. If it's not under warranty, I would keep an eye on it especially if you put aggressive loads on your wheels (mtb, touring, etc).
