HAProxy with LVS-DR

Hi,

I am having small architecture of two apache server with LVS loadbalancer in DR mode. I've installed haproxy (1.3.20) in front of eache apache server to protect them against slowloris with this haproxy config:

global

        daemon
        user hpr
        group hpr
        maxconn 20000
        pidfile /var/run/haproxy.pid
        stats socket /var/run/haproxy.stat mode 600

defaults
        mode http
        maxconn 4096
        timeout client 60s
        timeout server 60s
        timeout queue  60s
        timeout connect 4s
        timeout http-request 5s
        option httpclose
        option abortonclose
        balance roundrobin
        option forwardfor
        retries 2
        errorfile 503 /usr/local/etc/haproxy/errorfiles/503sorry.http

frontend public
        bind external_ip:80
        default_backend apache

backend apache
        option httpchk OPTIONS * HTTP/1.1\r\nHost:\ www
        server dwww1 127.0.0.1:80 maxconn 248 check port 80

listen stats
        bind       :8888
        stats enable
        stats hide-version
        stats uri     /
        stats realm   dwww1\ statistics
        stats auth    admin:admin
        stats refresh 5s

everything seems to be ok, but unfortunately after couple seconds apache is stop responding and haproxy send a lot of 503 errors

Aug 14 13:04:00 dwww1 haproxy[12565]: 95.*.*.*:39283 [14/Aug/2009:13:03:48.680] public apache/dwww1 16/0/-1/-1/12032 503 34 - - sC-- 49/49/49/49/2 0/0 "GE
T / HTTP/1.0" i also trying to disable keepalive and running only one apache server (one with haproxy) in LVS with no luck
when i omit LVS everthing works. Does anybody have similar problems with running haproxy with LVS-DR ?

Kind regards,
