    This is not normal behavior as far as I know.
    When no network options is specified the behavior is to default to 
    --network=smp, unless some other default has been set in the global 
    upcc.conf file or the user's ~/.upccrc.
    So, I don't know why you would have success with -network=udp and a link 
    failure without it.
    As soon as I have a chance I'll see if I can reproduce anything similar.
