I was able to reproduce apache returning connection refused for high load, but I agree that this is likely caused by our haproxy configuration. One tweak we could do is switch from workers to event for apache as that was the default for redhat but not ubuntu which in my testing seems to reduce the occurrence of the connection issues that I saw.
