Yes, the TCP/IP stack could be responsible for the enhanced fairness.
I'll check that.

But I am still curious: if a process calls MPI_Recv(..., MPI_ANY_SOURCE, ...)
and there are several messages pending that match this receive, how
does LAM decide which message to choose? And does this protocol take
measures to prevent a communication from starvation?

Stephan
