Many requests to /php_fpm_status and server unresponsive

Question

The server became very slow and unresponsive and I restarted apache and nginx a few times. I looked in my Apache mod_status page and I seen 10-20 requests to /php_fpm_status , besides 100-200 normal requests (timing out) to normal website urls.

• Does Apache or PHP make requests to /php_fpm_status when [re]starting the web server ?
• Or requests to /php_fpm_status are more likely abusive requests from outside ?

Answer 1

In PHP site we can see that:

For security the FPM status page should be restricted to internal requests or known client IPs only as the page reveals request URLs and information about available resources.

You can disable the FPM status safely if you don't need it.
