I've also had someone run into the endpoint busy problem. I never  

figured it out, I just increased the default endpoints on MX-10G  

from 8 to 16 endpoints to make the problem go away. Here's the  

actual command and error before setting the endpoints to 16. The  

version is MX-1.2.1with OMPI 1.2.3:

node1:~/taepic tae$ mpirun --hostfile hostmx10g -byslot -mca btl

Process 0.1.3 is unable to reach 0.1.7 for MPI communication.

If you specified the use of a BTL component, you may have

forgotten a component (such as "self") in the list of

usable components.
