For me, it took one tire spin and then suddenly catching on cemetery (red) at rausch. Very little throttle, just the weight of the jeep combined with the tire catching all at the wrong time.
The reason the 44 is that much stronger is the larger pinion gear, deeper tooth mesh/more tooth contact, and the factory locker or your quality aftermarket lockers are 4 pinion. Open D30 carrier is 2 pinion. Half the strength right there.

Wheeling smart has everything to do with it. And lockers help tremendously despite what people say (I drank the "open dif is less likely to break" koolaid for too long and learned the hard way).

Or.....could it have been a weakening of your axle guts from all that welding you did for the truss?

Define HARD? Hard trails, or "I'm an idiot with the skinny pedal hard"?
My 07' X was locked with 38's on pintler locks, trussed , gusseted, 5.13's and a Ripp SC. after 5 years the only thing that went was the drivers side U-joint. That Jeep did the Rubicon, Moab EJS 3 times, trails all over Oregon, WA state, SoCal, Badlands, Gulches, Rausch URE, and others. My relatively new '12 Sport has been running nearly a year on TWF's, locker, trussed and gusseted. It's handled east coast "HARD" trails with no issues on 3.73's.
Wheel smarter not harder. The only real difference the 44 gets you the larger gear set. Thicker pinion, yes an improvement, but If you don't torque the shit out of the 30 and pick smart lines, it will last on 37's.

We see a ton of jeeps go in and out of the shop weekly, montly and yearly. Its not uncommon for a Dana30 or a Dana44 to break with 37's or 35's.

I consider broken axle shafts and u joints to be part of the game. It can and will happen on just about any axle.
