Greetings Gunnar.

Can you provide all the information listed here:

    http://www.open-mpi.org/community/help/

For example, what version are you using? We had some bugs in the TCP
connection code dealing with multiple networks that were recently fixed.
Could you try the latest 1.1.1 beta and see if that fixes your problem?
