Spanning tree melt down ?
Anyone have any idea what really happened : http://www.boston.com/dailyglobe2/330/science/Got_paper_+.shtml <snip> It was too late. Somewhere in the web of copper wires and glass fibers that connects the hospital's two campuses and satellite offices, the data was stuck in an endless loop. Halamka's technicians shut down part of the network to contain it, but that created a cascade of new problems. The entire system crashed, freezing the massive stream of information - prescriptions, lab tests, patient histories, Medicare bills - that shoots through the hospital's electronic arteries every day, touching every aspect of care for hundreds of patients. ... The crisis had nothing to do with the particular software the researcher was using. The problem had to do with a system called ''spanning tree protocol,'' which finds the most efficient way to move information through the network and blocks alternate routes to prevent data from getting stuck in a loop. The large volume of data the researcher was uploading happened to be the last drop that made the network overflow. Regards Marshall Eubanks
