Hello,
It seems that haproxy don’t calculate current session properly, as you can see the on screenshot below.
I’m running : HA-Proxy version 2.0.17-1~bpo10+1 2020/08/02 - https://haproxy.org/ and the configuration for this part is quite basic.
On the server ss -ntp | grep ESTAB | grep X.X.X.X:3128 | wc -l give me 1732 which is more close to the sum of current session.
I didn’t restart or reload the process yet.
Any idea why it happends?
