Nope, just search for "Palword Dedicated Server RAM usage", keep in mind this is a Early Access game and the developers maybe have to fix a few things in order that the server is running fine.
There are many workarounds out there for preventing this but I don't want to implement a workaround since this can cause corrupt saves and other funny bugs.
However I would recommend that you restart the container once a day to lower the usage but I assume if you build more and more on the map the RAM usage will go up and up like it was back in the day the same for Valheim.
You could also limit the amount of RAM the container can utilize but if it reaches that utilization it will crash and restart, which is similar like if you restart it but this could also lead to a corrupt save game.
I've limited it to 20GB and experienced a crash yesterday with seven players on the server but it restarted just fine and a little progress was lost.
