When you restart HAProxy just the attempted binds > 1017 fail with the error: [ALERT] 045/222808 (22746) : Starting proxy VIP_Name: cannot create listening socket However on further testing this seems to be because I am calling the restart script from within Apache/PHP: >From the command prompt: haproxy -f /etc/haproxy/haproxy.cfg -p /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid) WORKS haproxy -f /etc/haproxy/haproxy.cfg start haproxy -f /etc/haproxy/haproxy.cfg stop ALL work fine... But from within Apache/PHP/Sudo `sudo /usr/local/sbin/haproxy -f /etc/haproxy/haproxy.cfg -p /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid) 2>&1`; `haproxy -f /etc/haproxy/haproxy.cfg start`; `haproxy -f /etc/haproxy/haproxy.cfg stop`; FAILS for > @1000 ports.... So shouldn't effect other people in the same way... I will investigate offlist.... -- Regards, Malcolm Turnbull. Loadbalancer.org Ltd. Phone: +44 (0)870 443 8779 http://www.loadbalancer.org/
