Hello List,
The -Vd output is:
root#sunexplor # ./haproxy -f digitel.cfg -Vd
[WARNING]
125/093451 (2187) : parsing [digitel.cfg:34]: keyword 'redispatch' is
deprecated, please use 'option redispatch' instead.
Available polling systems :
poll : pref=200, test result OK
select : pref=150, test result OK
root#sunexplor # Message from syslogd#localhost at Mon May 5 09:34:54 2008 ... localhost haproxy[2188]: proxy backend3 has no server available!
Message from syslogd#localhost at Mon May 5 09:34:55 2008 ... localhost haproxy[2188]: proxy backend2 has no server available!
There is no connection errors in syslog
The
test was stablish as 2 scenarios: a) test using haproxy, 1 client and 1
backend. b) the same client and the same backend but w/out haproxy. In this case, 200 threads x 200 seconds loading 10k html file each time
We have observed 100 connection at top load + 100
queue in haproxy console in apache3. I don't know if this is associated
to 200 poll available as -Vd display
Which client?, pylot 1.1, command line mode (http://www.pylot.org)

Sorry wrong platform!
epoll is only available on linux based system.

Sorry but I can't see the output of
./haproxy -f examples/haproxy.cfg -Vd
With which tool do you make your tests?
What is your backend?
How looks your haproxy.conf?
Have you any errors in the haproxy logs?
