Linux Web on amd64 high ram usage

[icabraja]

Hello!

I have repurposed an old Qnap NAS with 2GB of DDR3 RAM and an Intel Atom D525 running Debian 13. I have an issue with RAM usage after few minutes (it's idling in that time, no downloads are running) which renders the server unresponsive. Could this be some kind of a bug or this box is just underpowered for gopeed?

Aug 02 20:50:54 nas gospeed[1389]: Server start success on http://[::]:9999

This is my systemd service file:
