Is this a TCP-based cluster?
yes
If so, do you have multiple IP addresses on your frontend machine?
Check out these two FAQ entries to see if they help:
http://www.open-mpi.org/faq/?category=tcp#tcp-routability
http://www.open-mpi.org/faq/?category=tcp#tcp-selection
ok, using the internal interfaces only fixed the problem.
Per the tcp-routability FAQ entry, were our heuristics incorrect
about deciding which IP address(es) to connect to? E.g., did all
your interfaces have public IP addresses, or something else that went
against our assumptions?
