How do you install these patches into a working environment on ubuntu?
I am on version 1.4 but was curious how to do a patch install ?

But my concern is that it's exactly what haproxy is doing itself by doing
a setrlimit() upon startup. Thus I still fail to understand why it does
not work in your case.
Hmmm looking at the code I think I have an idea. It looks like the IP ranges
only reserve one socket (1 per "bind" line instead of one per port).
OK I found it. It was even worse than that. The setrlimit() is called AFTER
binding all the ports ! So it means that in your case, only the system's
limits are considered :-(
I've successfully reproduced your case and confirmed the attached patch fixes
it. I'll merge it, so feel free to apply it to your version.
Thanks for the report,
Willy
