Help!

Hello All.
When haproxy seamless reload config file, all health checks refresh to state “ok”, so backends become UP and receiving connections for few seconds.

Haproxy starts by command:
haproxy -D -f /usr/local/etc/haproxy/haproxy.cfg -p /var/run/haproxy.pid -x /var/run/haproxy.sock -sf $(cat /var/run/haproxy.pid)

Haproxy cfg for nbproc >1 has string:
stats socket /var/run/haproxy.sock mode 660 level admin expose-fd listeners process 1

and health check strings:

  1. Before reload:
    dump the current states to file, using haproxy stats socket and command “show servers state”
  2. Set haproxy.cfg to read this file like:
    server-state-file-name /tmp/haproxy_server_states
    load-server-state-from-file local
