问题描述

emqtt_bench 压测 Haproxy 连接数超过5千 压测程序就报错。
1.不经过haproxy，直连emqx连接数能达到5万。排除emqx问题。
2.用lvs替换haproxy，连接数也能上5万。排除负载均衡服务器问题。
3.问题就处在haproxy。

# to have these messages end up in /var/log/haproxy.log you will

# need to:

#

# 1) configure syslog to accept network log events.  This is done

#    by adding the '-r' option to the SYSLOGD_OPTIONS in

#    /etc/sysconfig/syslog

#

# 2) configure local2 events to go to the /var/log/haproxy.log

#   file. A line like the following can be added to

#   /etc/sysconfig/syslog

#

#    local2.*                       /var/log/haproxy.log
