Perhaps it's the situation rather than the person? Ive worked in high pressure environments before and a little bit of venting is incredibly tame. From the sounds of it whenever there is a crises he is the one expected to take care of it. The easiest way to fix it is to take on a chunk of the responsibility yourself. At the very least it will give you a better understanding of the pressure he is under. If I have to work through the weekend fixing critical problems caused by careless coworkers then I'll probably have a whinge. If you make me miss out on spending time with my wife and kids.... Of course I'll be a bit frustrated with you.
