您好，我们使用haproxy 卸载tls并代理emqx，大概代理了24w连接，在前期运行的很好，不过在大概10天左右，会出现以下问题：
- 健康检测time out；
- 设备部分掉线，重连时无法新建立连接；
在此时直连是正常的。
haproxy配置如下：
global
maxconn 130000
log 127.0.0.1 local0 debug
#log 127.0.0.1
#log loghost local0 info
uid 995
gid 993
#daemon
#cpu-map 1-4 0-3
nbthread 2
#debug
#quiet
chroot /usr/local/haproxy
stats socket /run/haproxy-master.sock mode 600 level admin
maxsslrate 169
#profiling.tasks auto
#tune.runqueue-depth 2000
spread-checks 5
These parameter can be used for frontend, backend and listen:
defaults
log global
mode tcp
retries 3
# maxconn 520000
balance roundrobin
balance source
balance leastconn
option clitcpka
frontend stats
bind *:8404
mode http
http-request use-service prometheus-exporter if { path /metrics }
stats enable
stats uri /stats
stats refresh 10s
listen admin_stats # The name of the Stats page reporting information from frontend and backend. You can customize the name according to your needs.
bind 0.0.0.0:8080 # The listening port.
mode http # The monitoring mode.
option httplog # Enables HTTP logging.
maxconn 10 # The maximum number of concurrent connections.
stats refresh 30s # Automatically refreshes the Stats page every 30 seconds.
stats uri /haproxy # The URL of the Stats page.
stats realm HAProxy # The authentication realm of the Stats page.
stats auth admin:xxxxx # User name and password in the Stats page. You can have multiple user names.
stats hide-version # Hides the version information of HAProxy on the Stats page.
stats admin if TRUE # Manually enables or disables the backend server (supported in HAProxy 1.4.9 or later versions).
frontend frontend_emqx_ssl

option tcplog
timeout client 200s

官方推荐使用haproxy代理，请问那个版本的haproxy比较稳定？
