Because this was the main kevent() call, I think it means that the time limit was invalid. But I wonder what exactly that means. Is it too low or too high? Do you have a core dump you could debug? Would be interesting to see what the value of "ts" is. Or you could try adding the attached patch and if it happens again, it would log ts's value.
