httpd/php log duplication

The problem

Here's a fragment of the output of docker compose logs showing the exact same php notice:

legulas_php      | NOTICE: PHP message: PHP Notice:  Undefined index: autenticado_painel in /var/www/public/taruma/index.php on line 3
legulas_httpd    | [Thu Apr 14 22:29:02.944401 2022] [proxy_fcgi:error] [pid 10:tid 140303436561208] [client 172.19.0.1:39244] AH01071: Got error 'PHP message: PHP Notice:  Undefined index: autenticado_painel in /var/www/public/taruma/index.php on line 3', referer: http://localhost/

The same happens to access logs:

legulas_php      | - -  14/Apr/2022:21:49:15 +0000 "GET /eadlegulas/meusDadosSeguranca.php" 200
legulas_httpd    | 172.19.0.1 - - [14/Apr/2022:21:49:15 +0000] "GET /eadlegulas/meusDadosSeguranca.php HTTP/1.1" 200 7015

This could be a simple configuration problem, but I couldn't figure it out by myself.

Details

php Dockerfile:

FROM php:7.4-fpm-alpine AS php

COPY ./zz-pool.conf ${PHP_INI_DIR}/../php-fpm.d/

Pool configuration (zz-pool.conf):

[www]
listen = /var/run/php-fpm/php-fpm.sock

httpd Dockerfile:

FROM httpd:2.4-alpine AS httpd

httpd proxy configuration:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so

<FilesMatch "\.php$">
    <If "-f %{REQUEST_FILENAME}">
        SetHandler "proxy:unix:/var/run/php-fpm/php-fpm.sock|fcgi://dummy/"
    </If>
</FilesMatch>

This sounds similar to #878 (comment)

Thanks. Turning off fastcgi.logging eliminated the duplicated error logs.

fastcgi.logging = 0

Access logs continue duplicated, though, but that's ok.

I just hope this doesn't end up hiding important logs that don't show up anywhere else.
