my nextcloud server uses too much RAM (apache)

I'm using Apache with following configuration:

Timeout 60
KeepAlive On
MaxKeepAliveRequests 100
<FilesMatch \.php$>
        SetHandler "proxy:unix:/var/run/php/php7.4-fpm.sock|fcgi://localhost/"

          MaxClients           60
          MaxRequestsPerChild 1000
</IfModule>

Then this is my external.conf (where the traffic from varnish's gonna be encrypted):

<VirtualHost *:443>
        Protocols h2 http/1.1
        ServerName cloud.privacyy.ch

        Include /etc/letsencrypt/options-ssl-apache.conf

    </IfModule>

    <FilesMatch "\.(js|css|php)$">
           Header set Cache-Control "max-age=63072000, private"
    </FilesMatch>

</VirtualHost>

This is internal.conf:

        protocols h2 http/1.1

    DocumentRoot /var/www/html
    <FilesMatch \.php$>
        SetHandler "proxy:unix:/run/php/php7.4-fpm.sock|fcgi://localhost/"
    </FilesMatch>

    <IfModule mod_headers.c>
            Header always set Strict-Transport-Security "max-age=15552000; includeSubDomains; preload"

        </FilesMatch>
</VirtualHost>

Please note that I didn't include comments or like log-settings here

When I download anything using the web browser the apache server's using more and more ram (and uses whole 12.3GB swap even if I don't download a 12.3GB file) and the download speed's decreasing. The same happens when using Nextcloud (desktop/phone) apps

The original download speed was 10MB/s

I've enabled following apache mods:

access_compat alias auth_basic authn_core authn_file authz_core authz_host authz_user autoindex deflate dir env expires fcgid filter headers http2 mime mpm_event negotiation pagespeed proxy proxy_balancer proxy_fcgi proxy_http reqtimeout rewrite setenvif slotmem_shm socache_shmcb ssl status unique_id

I'm using a maria database (recently switched but didn't do much)

Nextcloud's using redis-server as a php cache and I've enabled opcache with the nextcloud's recommended settings. I disabled that already to test but that didn't solve the problem.

Only apache's using that much RAM - everything else's fine Also the things don't get removed from the RAM(&swap) until I reload/restart the apache server

When downloading from the browser the download just stops at 383MB - and the browser doesn't say how large the file is to download (Onedrive has that issue too with less than 1MB/s download speed on larger folders, it's like: unknown time remaining - how-much-already-downloaded - download speed)

What did I configure wrong? Or is it something else?

My server's an apple macbook air 4GB RAM 2GHz - 2.2GHz(boost) Intel multithreaded 2 core cpu, xanmod kernel If there's something missing, notify me One thing: earlyoom kills the apache server if there's no free RAM Another thing: I'm on Ubuntu21.04 without x-server and 400MB RAM usage if there's nothing going on

Questions should demonstrate reasonable information technology management practices. Questions that relate to unsupported hardware or software platforms or unmaintained environments may not be suitable for Server Fault. An Laptop is never a server

Additional information : I believe that the cache is your issue... try a look for like https://ubiq.co/tech-blog/disable-apache-cache/

As you see I don't have the modules cache and disk cache enabled so why does the apache server cache anyways?

you were wrong - I disabled all caching I made by myself but it didn't do anything except make the page loading slower

but I noticed that the RAM got free afterwards so I'll look for other caching

Disable Modsecurity body-scanning and bypass the varnish cache for downloads

Here's an issue: https://github.com/varnishcache/varnish-cache/issues/2964

I completely dropped varnish because it's zero performance improvment and varnishncsa uses much cpu (1-2% on idle)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
