So that I am the only gremlin there. (Last time I saw split-brain was when I myself pulled on the x/over cable. Really. If you have an rj45 connector with the little tab broken off, throw it out and get a new one now. Trust me, it's much cheaper than the alternative.) Seriously, though, you have to weigh the cost of ipmi daughterboards or net-connected power strips vs the likelyhood of losing that cross-over link vs the likelyhood of the power strip itself going titsup and taking down your entire cluster. *Then* say "go get a real stonith device".
