Ooops. This should have been "But what might cause it?" > > Are you running IB multicast (e.g. IPoIB) ? That's the most common > cause. IPoIB is up, but so far only used initially by lustre for initial lnet o2ib setup, but then AFAIK not any more. I think some MPI stacks/applications also do their intial connection using IPoIB. But in general, once these connections are established, IPoIB is not much used anymore.
