Hello,
I'm running HAproxy with this version

HA-Proxy version 1.7.3 2017/02/28
Copyright 2000-2017 Willy Tarreau willy@haproxy.org

I have this config of haproxy

global
    stats timeout 30s
    maxconn 5001
    
defaults
    option httplog
    option dontlognull
    retries 3
    mode http
    timeout connect 5000
    timeout client  50000
    timeout server  50000
    
frontend https-in
    bind *:443
    log 127.0.0.1 local2
    mode tcp
    option tcplog
    timeout client  3h
    timeout server  3h
    option          clitcpka
    use_backend back_webapp_apache2_php56-443
    
backend back_webapp_apache2_php56-443
    mode tcp
    balance roundrobin
    server host0 10.0.4.59:443 check fall 3 rise 2

So I have one apache backend running at ip 10.0.4.59.

The problem is sometimes I'm getting this error.

https-in https-in/ -1/-1/0 0 SC 0/0/0/0/0 0/0

Sometimes it is working. But connection is not consistent. What can be the issue HAproxy or Apache ? I don't know where to start debug this issue.

Thanks & Regards,
Chintan Patel
