When starting the rrul46compete test, I noticed some weird behavior:

With defined hosts mn.h1 and mn.h2, each having an IPv4 as well as an IPv6 address, the command
sudo flent rrul46compete -p all_scaled -l 60 -H mn.h2 -o rrul46_nolocal.pdf -v
runs error free with complete graph output.

However, specifying a --local-bind, the TCP connections for IPv4 fail at some point and their respective lines in the graph are missing:
Changed command:
sudo flent rrul46compete -p all_scaled --local-bind mn.h1 -l 60 -H mn.h2 -o rrul46_new.pdf -v

Error output (same for upload BK, download BE and download BK respectively):
