This topic has been discussed a few times before. It's typical for the wood to get small "cracks" and discolor a bit. NO LEAKS, just cosmetic issues. To stop the progression, I painted on small amounts of polyurethane on the cracks to keep water from penetrating the VERY thin layer of wood.
Should this happen? Probably not, but it seem to be the norm with wood boards that are a few years old.
