Advice to Prevent Zirconia Bridge Warpage?

Anyone have any advice on zirconia bridge frameworks "warping"? Hardly ever happens with frameworks with no curve, but seems to be more frequent with 4 unit and larger frames that curve (anterior). Individual units fit terrific internally and marginally, but 2-3 out of 10 times the frames will rock slightly. We are sintering these alone with no rapid sintering cycles.
