We used to get this practically for every node in our cluster until we turned on "Edge port" or "Fast link" in the Spanning Tree configuration on our Dell PowerConnect 5224 GE switches.

It looks like the network card decides it has link before the switch is willing to pass traffic to it. -- Humberto Ortiz Zuazaga Programmer-Archaeologist High Performance Computing facility University of Puerto Rico http://www.hpcf.upr.edu/~humberto/
