nginx: worker process is shutting down

[yoni]

Good morning,

On our WAPT server, the nginx services saturate the RAM (Memory: 10.6G (peak: 11.4G)), the nginx processes fall.

Code: Select all

Main PID: 1370 (nginx)
      Tasks: 75 (limit: 100195)
     Memory: 10.6G (peak: 11.4G)
        CPU: 18min 11.549s
     CGroup: /system.slice/nginx.service
             ├─ 1370 "nginx: master process /usr/sbin/nginx"
             ├─ 1891 "nginx: worker process is shutting down"
             ├─ 1895 "nginx: worker process is shutting down"
             ├─16158 "nginx: worker process is shutting down"
             ├─16160 "nginx: worker process is shutting down"
...

             ├─66534 "nginx: worker process is shutting down"
             ├─66536 "nginx: worker process is shutting down"
             ├─71634 "nginx: worker process"
             ├─71635 "nginx: worker process"
             ├─71636 "nginx: worker process"
             ├─71637 "nginx: worker process"
             ├─71638 "nginx: worker process"
             ├─71639 "nginx: worker process"
             ├─71641 "nginx: worker process"
             └─71642 "nginx: worker process"

How to optimize the nginx service?

I followed the recommendations below https://www.wapt.fr/fr/doc/wapt-server- ... ation.html.

The /var partition is not full. On Red Hat, the nginx directories are in /var/lib/nginx/tmp/proxy/.

In addition:
curl http://127.0.0.1/nginx_status
Active connections: 1883
server accepts handled requests
129746 129746 133154
Reading: 0 Writing: 1880 Waiting: 3

Red Hat Server 9.7
Wapt Enterprise 2.6.1.17765

Thank you for your help
