I have not personally used that line before, but the picture clearly shows that the issue is not normal wear and tear but likely shrinkage or installation/moisture related movement. While I would check the humidity levels and expansion gaps before anything else, if I was seeing this many boards spitting I would likely submit a warranty claim with manufacturer.

This is common with character grade hardwood as it's minuscule.

What do mean it is common? we have 60 boards that cracked and our humidity is at 36-40 degrees. The manufacturer is replacing 900 sq feet of floor but i am worried it will happen again.

I guess yours is uncommon. I thought you were worried about one board against the wall that nobody would see anyway. Perhaps the hardwood moisture content was too high during the installation. This would result in surface cracks.
