Как убрать ошибку nginx Failed to read PID from file /run/nginx.pid: Invalid argument?

Question

[Кирилл Казаков]

Nginx работает , но смущает ошибка :
#service nginx status

systemd[1]: Failed to read PID from file /run/nginx.pid: Invalid argument
systemd[1]: Started A high performance web server and a reverse proxy server.

# cat /run/nginx.pid

9953

ls -la /run/nginx.pid

-rw-r--r-- 1 root root 5 Jul 3 03:21 /run/nginx.pid

Или nginx не может найти перед запуском файл (после рестарта например), далее его создает и далее нормально стартует ?
В error.log - пусто .

Upd1:

service nginx status

Закомментировал. Не помогло. pid там же создается.

cat /etc/nginx/nginx.conf | head -n 50
