What happened?

We currently we have a Dungeon server that will create a randomly generated dungeon which is a new world and after it's completed it will unload it. The dungeons doesn't contain ANY custom noteblock blocks and only retextured blocks. After some time the server will eventually crash du to the ram usage being fully used.

After some digging we found out that the issues was itemsadder in the class "ia.m.ad, field e" of itemsadder where it will keep a reference of an unloaded world, maybe the "Fast and Optimised file system" could be disabled in some way ?

Here are some results that we got from our big research:

Steps to reproduce the issue

Load and unload dozens of worlds every minute
have 10-40 players in them
wait 1-3h
crash
