Backend server maxconn is ignored

Hello,

I have a question: I’ve set the maxconn on a per backend server basis but that limit just seems to be ignored. Please see the attach picture:


The backend config is:

backend wbidders
retry-on all-retryable-errors
mode http
fullconn 300000
option http-server-close
option httpchk
http-request del-header X-Forwarded-For
option forwardfor
http-request set-header X-Forwarded-Port %[dst_port]
http-request add-header X-Forwarded-Proto https if { ssl_fc }
# Balancing algorithm
balance leastconn
timeout connect 5s
timeout check 2s
# Backend servers
server wbidder0 172.16.7.240:8080 tfo check weight 10 maxconn 1900
server wbidder5 172.16.7.245:8080 tfo check weight 10 maxconn 1900
server wbidder6 172.16.7.246:8080 tfo check weight 10 maxconn 1900
server wbidder7 172.16.7.247:8080 tfo check weight 10 maxconn 1900
server wbidder8 172.16.7.248:8080 tfo check weight 10 maxconn 1900
server wbidder9 172.16.7.249:8080 tfo check weight 10 maxconn 1900

Any idea what happens?
