This is great to know. I was having issues with dropped OSC messages just from newer ipads sending way more messages than older ones.
I ran:
sudo sysctl net.inet.udp.recvspace=1573792
on the command line in macos and my received messages went from 8197 to 10000. I did have to recompile the class library after running that command.
you can see the current setting with:
sysctl -a|grep net.inet.udp
