Hi

I’m having 2 issues with below systemctl script with RHEL 7.X

1. I’m seeing below error frequently in systemctl status haproxy-80 or 443 instance

systemd[1]: [/etc/systemd/system/haproxy-80.service:11] Failed to parse kill mode, ignoring: mixed  
systemd[1]: [/etc/systemd/system/haproxy-80.service:11] Failed to parse kill mode, ignoring: mixed

systemd[1]: [/etc/systemd/system/haproxy-80.service:11] Failed to parse kill mode, ignoring: mixed

1. More importantly, after few days HAPROXY unable respond and health checks are failing. I am pretty sure backend is working fine. restarting the haproxy immediately fixing the issue. There is no pattern but it has been happening very frequently. As always, restarting haproxy resolving the issue immediately

I am using a self compiled version of haproxy and below are compiled flags

My systemctl startup script

cat /etc/systemd/system/haproxy-80.service  
[Unit]  
Description=HAProxy Load Balancer  
After=syslog.target network.target

[Service]  
Environment=“CONFIG=/opt/haproxy/haproxy-80/conf/haproxy.conf” "PIDFILE=/run/haproxy-80.pid"

ExecStart=/opt/haproxy/haproxy-80/sbin/haproxy-80-systemd-wrapper -f $CONFIG -p $PIDFILE  
ExecReload=/opt/haproxy/haproxy-80/sbin/haproxy-80 -f $CONFIG -c -q

.i am running 80 and 443 instances separately thus. binaries are shared but using different configuration files.

Can you confirm above systemctl startup script is valid ?
