1650	Active connections not clear close session	kfir.snunit.org.il@…		"Hello,
I've been trying for a while to figure out what is the problem for unclosed session, without success.

At least once every two days I see more then 1000 active connections under nginx by run this command:
curl -s http://127.0.0.1:1337/nginx_status

But actually I see that there are only 300 connections to the server under port 80 and 443 together:
netstat -anp | grep :80 | grep ESTABLISHED | wc -l
netstat -anp | grep :443 | grep ESTABLISHED | wc -l

And that number can continue to grow until I restart the service:
service nginx restart

It started to happen since I installed the official version from your repo instead of the official version from the ubuntu repo.
From v1.14.0
To v1.15.2
The same issue.

Plaece advice...

Regards, Kfir Man
