we have had some serious buckling in our living room as well and it seems to be in one of the highest traffic areas that has no furniture holding it down. It has been in for about a year now and it started about 6 months ago. I heard a tip from a local flooring expert that is a friend and he suggested using screws every 3 feet along the walls and put quarter round on top of it so you get the look and less movement at the edges. I am working on it today so i will try to respond with how well it works...
