What I was trying to get at is *if* the problem really is with FreeBSD, there should be more than just me looking into it given the implications of what that would mean. The worst case scenario is that this is 100% a FreeBSD problem, and that would have some fallout. In my previous work, we had to map out every possibility and plan for it -- we didn't have the luxury of determining the fault and then coming up with a plan. That mentality is carrying over probably. > > It sounds like you're advocating for just removing an assertion without > proving it's a false positive.

I don't have any preconceived notion of the cause of the fault nor the solution. My mind is wide open at this point. John
