Debian & rust server

Hi guys.
The problem is that the game server uses a lot of RAM. Namely, more than 8.5 gigabytes. Only 7 plugins installed. Vanish, AdminRadar, Rustcord, RemoverTool, DeathNotes, DynamicPopulation, StackSizeController. Map type Procedural Map, size 4800. What could be wrong?

I couldn't find any information on this topic on the Internet :(

That is normal RAM usage for your setup.
