I am using HAProxy on RedHat 5.5 and have below configuration.

global

    daemon

    maxconn 1024

    log  127.0.0.1  local1 info



defaults

    log global

    balance roundrobin

    mode http

    retries    3

    option redispatch

    timeout connect 300000ms

    timeout client  300000ms

    timeout server  300000ms



listen epgs

    bind *:80

    server server1 127.0.0.1:8080 maxconn 1 check

    server server2 epg.local.com:8080 maxconn 1 check

    stats uri /stats

I started firing 5000 request to HAProxy using JMeter. While JMeter is firing 
the request I removed the server2 from configuration file and fired "haproxy -f 
/etc/haproxy.cfg -p /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid) 
command. I noticed 2 connection refused errors in JMeter log.

2012/01/11 03:31:31 ERROR - jmeter.protocol.http.sampler.HTTPJavaImpl: 
readResponse:  java.net.ConnectException: Connection refused

2012/01/11 03:31:31 ERROR - jmeter.protocol.http.sampler.HTTPJavaImpl: 
readResponse: java.net.ConnectException: Connection refused

2012/01/11 03:31:31 ERROR - jmeter.protocol.http.sampler.HTTPJavaImpl: Cause: 
java.net.ConnectException: Connection refused

2012/01/11 03:31:31 ERROR - jmeter.protocol.http.sampler.HTTPJavaImpl: Cause: 
java.net.ConnectException: Connection refused

Do you know which configuration I should use to make HAProxy not drop any 
request and am i verifying it correctly too?

Thanks for your help in advance.
