On one of our Stabilizers, we lost contact between the pin highlighted in this picture and the polygon. I believe the reason was repetitive mechanical stress on the connector due to frequent power-cycling.
Reflow of the solder did not fix it, only adding a solder bridge to the closest exposed copper did, so I think the problem was the width of the thermal relief.
