Hetzner AMD VPS 2GB has memory leak with OpenMPTCProuter (server stops responding to SSH after 24 hours)

Expected Behavior

VPS server should not freeze (no response to SSH)

Current Behavior

Clean install of OpenMPTCProuter script (v0.6 current stable) on Debian 12 using Hetzner web interface. The VPS freezes after about 24 hours of usage, the only solution is reset via Hetzner web interface and then it's good for another 24 hours.
Server does not respond to SSH connections. Hetzner AMD VPS 2 GB RAM, larger swap does not fix it. Reinstall of the OS does not fix it. Upgrade to larger RAM does not fix it (we tried 4 GB RAM).

Possible Solution

We already cancelled the VPS so we can't really debug it further, consider yourself warned, if anybody is interested to debug this feel free to do so.

Workaround no1: Get Hetzner dedicated server (anything works - we got the budget one from "auction"). Be warned the routing might be a bit different for each of their datacenters). Workaround no2: Get VPS from OVH (only tested the 4GB RAM). Works fine.

Steps to Reproduce the Problem

Install Debian 12 on Hetzner VPS (we had the AMD 2 GB RAM)
Install OpenMPTCProuter VPS script version 0.1030 6.1.0-22-cloud-amd64 (or whatever was available as "default" on 2024-06-11)
Use the OpenMPTCProuter router via the local machine for about 24 hours.
Memory leak occurs (see screenshot), hard reset workaround good for 24 hours.

Context (Environment)

Fresh install of Debian 12 + OpenMPTCProuter VPS script, nothing else. Hetzner VPS AMD 2 GB.
