If you have access to x-ray, I would try to have a look through some of your joints.. What I am thinking is that the gassing of the board has something to do with pushing the plating out to the edges. If this is extreme enough to cause this problem, then you will probably also see a very pourus joint.
I was at B&O today, and asked the guys there if they had experienced anything similar, but they could not shed any more light on the subject.
If you have a close up of this problem, I would be interested to see it.
