All the walls are good, must be some movement in the ceiling. From the corner of the tray ceiling to the wall (about 2 feet) is the narrowest part of a 40' run of sheetrock. The info I have is there should be an expansion joint if the run is over 30'. I might put extra supports in the attic and try a repair one more time but an expansion joint would fix it for sure.
Maybe a ceiling fan introducing vibration?
