Ephemeral port exhaustion is easy to handle if you control HAProxy and the origins.

You'll need the source [1] option on your server lines, and you also need to adjust to allow more connections, one of these will do: have the origin server listen on more ports, add more ips to the origin server and listen to those too, add more ips to the proxy and use those to connect as well.

I'm not sure about handle exhaustion? I've run into file descriptor limits, those are usually simple to set (until you run into a code enforced limit)

I might be missing some details there to be honest; I'm more familiar with the application side of things than the infrastructure :)
