@abrarcv170 @bagsa Are you able to describe your setup, e.g. Apache, Nginx, PHP mod or PHP-FPM etc, also what version.

I found this, which might be related: https://bugs.php.net/bug.php?id=80739

It's working fine for us:

@estahn We're hitting the same issue and it definitely looks related to the php bug you linked. What version of PHP do you have it working on and which process manager are you using? I've tested on php73 and php74. I tried changing listen.backlog to other values but listen queue len still shows up as 0.

QUERY_STRING="json" SCRIPT_NAME=/status   SCRIPT_FILENAME=/status   REQUEST_METHOD=GET cgi-fcgi -bind -connect /var/www/php-fp

  "process manager": "static",

@estahn is your php-fpm listening on TCP/IP or Unix Domain Socket?

[estahn]

@estahn is your php-fpm listening on TCP/IP or Unix Domain Socket?

You can configure either, see README:

FastCGI address, e.g. unix:///tmp/php.sock;/status or tcp://127.0.0.1:9000/status

[glennpratt]

@estahn I understand. I'm asking in relation to this issue and the php-fpm bug linked. It may be that the queue stats are only available when using TCP.
