We are running HAProxy v. 1.5.4 in TCP mode and are running into an issue where down hosts are receiving traffic for a short time after HAProxy is reloaded. This eventually gets sorted out and traffic stops going to these hosts (after the healthcheck fails), however there is a spike in failures before this happens. I was looking through the manual to see if there was an option to deal with this case. The closest thing I found was redispatch, but this seems specific to HTTP proxied traffic to specific hosts. Has anyone ran into this issue before? Any suggestions?
