<div>Bob, the packet storm is not a forgotten concept. I've seen many a packet storm, and not that long ago.</div>
<div>On Beowulf clusters. Just think what happens if your Spanning Tree protocol goes wonky.</div>
<div>That's a reason why I'm no great lover of Ganglia too - it just sprays multicast packets all over your network.</div>
<div>Which really should be OK - but if you have switches which don't perform well with multicast you get problems.</div>
