I see a few things wrong in your two mails:

Your machine is apparently out of semaphores.  Standard mpich/p4
problem not related to mpiexec, but probably exacerbated by numerous
failures to start correctly.  Process 0 dies after that.

Process 1 tries to start and connect to this process 0 at the negotiated
port number, but it's gone so it too dies.

Read the mpich/p4 docs to learn about "cleanipcs" then try again from a
clean slate.
