Sorry, i send the previous mail in wrong format. Hello, I install haproxy 1.4 in a Debian Squeeze system, with a 2.6.32-5-amd64 kernel. The configuration is this:######global maxconn 5000 log 127.0.0.1 local5 info err stats socket /var/run/haproxy.sock mode 0600 level admin pidfile /var/run/haproxy.pid defaults mode http log global retries 3 option redispatch timeout contimeout 5000 timeout client 1800000 timeout srvtimeout 5000listen proxy-http *:80 mode http option httplog stats enable balance roundrobin acl rule1 url_dir news use_backend back-news if rule1 default_backend back-httplisten proxy-stats *:8080 mode http option httplog stats enable balance roundrobin server srv1 IP:80 stats enable #stats hide-version stats show-legends stats uri /admin?stats stats realm Haproxy\ Statistics stats auth user:pass stats refresh 5sbackend back-http option httpchk GET /test.txt http-check expect string OK server web01 IP:80 check inter 5000 fastinter 1000 downinter 1000 rise 2 fall 2 server web02 IP:80 check inter 5000 fastinter 1000 downinter 1000 rise 2 fall 2backend back -news server web03 IP:8080/news############I can start and stop haproxy withouth problem, but when i reload its configuration, it print the following: # /usr/local/sbin/haproxy -f /etc/haproxy/haproxy.conf -p /var/run/haproxy.pid -st $(/var/run/haproxy.pid) -bash: /var/run/haproxy.pid: Permission denied[ALERT] 303/172211 (6281) : Starting proxy proxy-http: cannot bind socket[ALERT] 303/172211 (6281) : Starting proxy proxy-stats: cannot bind socket I googled, but i can't find anything, in the same machine, there aren't any other service listen in these ports, only haproxy.
