I have a webserver with ispconfig (mysql & php & nginx). My munin statistic shows that there are the connecitons limited to about 9k. But I can't find a settings which is about 9000 which I could increase.
My system: Debian 9.8 / 128GB E5-1650v3 / nginx/1.10.3
My nginx settings are:
events {
worker_connections 768;
# multi_accept on;
}
Below are the the graphs which show the limit, all other graphs look normal.
Can you give me a hint which settings are responsible for the limited connections?
