Nginx Proxy Manager - Memory Usage unclear

I have an Ngnix Proxy Manager with 100 proxy hosts running on an ubuntu with 32GB Ram. However, the RAM usage is constantly increasing (and running out).

i see differences between top, free -m and docker stats that i can't explain. nothing else is running on the machine except the two containers for nginx proxy manager.

Some of the proxy hosts have chaching enabled, can this contribute to higher ram consumption?
Here are the configs for a proxy host:

in the logs i can't find anything conspicuous so far but i only see the access.logs now

can I start somewhere else here or am I missing something?

many thanks

mine is also spiking up when accessing an internal server like streaming from jellyfin.
jellyfin server is proxied through npm like this:

jellyfin.domain.com -> 192.168.0.2
