Hi, HAProxy 1.7.9 is being used to route traffic to a Kubernetes cluster on AWS. It was observed periodic spikes of RST from HAProxy on active connections. Full details in the following issue from GitHub: https://github.com/jcmoraisjr/haproxy-ingress/issues/77 . In which circumstances HAProxy send RST? Any help would be very much appreciated.

Hi, HAProxy will close TCP connections using RST if he is the initiator
of the connection, but it is not clear if this is the case here.
In the github issue it is written:
> That host only sends RST packets to all[2] connections from a single
client IP.
Are we talking about connections initiated or accepted by HAProxy ?

Also without providing logs and the conf, I can't be of a great help.
