only odd thing i can find in your logs is that in case of newer rtmpdump server is sending onBWCheck twice. probably it didn't like our BWResponse. there is one commit made on 02/08/2011 which is just after the working rtmpdump date 11/7/2011. you can try after reverting the changes made by this commit.

    Unexpected BW Response Fix

    Bug: SendCheckBWResult sends an invalid bw response due to casting issues
    from a double to an int.
