What happened?

Since the 1.19 update or even the 1.18 I have been getting crazy amount of lag in certain situations.

All in single player mode and sometimes multiplayer from single player.

1. Sitting in the menu for an extended period of time can cause massive lag because of the GC running rapidly as there is an expected memory leak
2. After player for over 2+ hrs in a session can cause the same GC running rapidly

This happens in the Other in my base there where I have everything. Only entities are 2x withers (1 always being killed and replaced) 1-12 bees, and an occasional mob farm running ~60 mobs per second. Each time the aforementioned issues happen the mob farm was not running.

Note: Forgot that pneumatic craft crop supports count as entities, have 384 of them. 256 in 1 chunk 128 in another.

At the time of the heap summary capture the software.bernie.geckolib.animation* series had allocated around 1.7GB of memory out of the 8.8GB allowed for this instance. This was captured right before the game crashed because the GC went absolutely crazy so I am not 100% on the geckolib-core, or what ever mod is using it, causing the issue.
