Question Very High RAM usage with 2-3 players on server

[oribiler]

Hi, I'm running a 1.19 minecraft paper spigot server on a VPS with 12GB Ram, Ryzen9 5900x, and I allocated -Xms128M -Xmx8G (with aikar's flags) for it, when I start and play on my server with 2-3 players on, my ram usage is about 3900-6000mb. why does it occur? I tried reducing ticks, still not working. I also receive low tps whenever I join the server or when someone "random teleports because of a plugin I need on a survival world" on the respective world. Here are my server timings, could someone help me please?

Here is a screenshot of my ram usage and plugins: https://prnt.sc/X3xsMPrAwiwx

Hey bud, I had a similar issue too running similar specs. After running /spark heapdump I found a Memory leak inside:

com.destroystokyo.paper.util.map.QueuedChangesMapLong2Object.

Paper have been told from what I've seen but there is still no fix. My best suggestion would be to run Spigot rather than paper until this issue is fixed.
