Having lot of waiting connection will cause high CPU usage?

Server NGINX
1

Hi,

In one of my server, the nginx status return the following

Active connections: 3595
server accepts handled requests
95329528 95329528 118118629
Reading: 334 Writing: 49 Waiting: 3212

There are a lot of “Waiting” connection, and the CPU load average is
around
2, I am using the default Keep alive timeout of 65s.

I am thinking what should be done in order to reduce the load average.
(I
am using SSL for the connection)

Thanks.

Could you post 10 line of this command :

Have you insert reset_timedout_connection directive to your conf?
