Hi,
I'm wonder what can cause HTTP error 408. Atm each day around 4-5k
requests ends with 408. Really random request also at random backends.
Already try change timeouts but doesn't change that number at all.
Thats my connections at 60-70% max bandwidth:
#v+
~ # netstat -ntu | wc -l
67121
#v-
Most important things from haproxy.conf
#v+
global
# log 127.0.0.1 local0
log 127.0.0.1 local1 notice
user nobody
group nobody
daemon
#debug
#quiet
nbproc 4
pidfile /var/run/haproxy.pid
maxconn 32000
defaults
log global
mode http
option httplog
option dontlognull
option redispatch
option httpclose
option srvtcpka
option forwardfor
balance roundrobin
retries 3
maxconn 8192
timeout client 30s
timeout connect 30s
timeout server 30s
then only backends and frontends sections (around 40 all)
