Description

Luckperms seem having memory leak problem, i am using luckperms 5.3.40 , when my server run for more than 7 hours, the memory problem start going bigger and bigger, i have done a heapdump after server have running for 7-8 hours, and the heapdump result show this:

Reproduction steps

1. run a server and wait for 5-6 hours+
2. get a heapdump
3. use the heapdump using eclipse

Expected behaviour

This problem makes my server G1 Old activate, by using aikar's flag, there should only be G1GC working, without memory leak, the server tps should be stable

i used the server i have memory problem to take this report, but turning the config setting on using lp reloadconfig

It seems like another plugin on your server is loading user data for lots of players at runtime then not unloading it. Doesn't appear to be a LuckPerms bug
