Trying to diagnose laminate swelling

My laminate flooring in my kitchen has started to swell in the last two weeks. It started with just the end joints butting up slightly, but now the seams along the length are starting to raise as well.

I installed the laminate flooring in my kitchen, adjoined dining room and living room over a wood sub base. The level below the floor is my garage.

The buckling is only occurring in the kitchen. A unique factor of the kitchen is that it is the only portion installed over existing linoleum. From what I've read that wouldn't cause a moisture problem?

Another unique factor with the kitchen is since it is attached to the dining room it is the longest span of the floor. Perhaps I didn't allow enough expansion room? Strange thing is the dining room (the other end)is perfectly smooth. Water has not spilled on it and I'm not aware of any appliance leaks.

It has been very humid lately, but the thing that has me stumped is that this is the third summer since its been installed and I haven't had any trouble in the past with humidity.

The flooring is Pergo Malaysian Kempas. It is roughly 1/2 the width of typical laminate so there are quite a few more joints.

Could I be missing something? Thanks.
