Paul is right. It's all fine and dandy to feed them huge meals while they are growing, but once they hit adulthood, you should cut back at least a little bit. But even at 6 feet, 3 jumbos is way too much. I had an almost 6 foot king that would take 3 normal adults or 2 jumbos, but any more than that is risky.
Something else to consider are your temperatures. If she's not being kept warm enough, regurge is almost inevitable. What are your cage temps?
