Memory leak source?

I believe I'm dealing with a memory leak on my server. Running 1.18.2-40.2.18 Forge (Java 21). Here's the modlist, some spark profiles, and a crash report as well from when it runs out of memory. This is an 8gb server (6.5gb allocated) through Witherhosting.

Spark profiles:
1 - https://spark.lucko.me/00d8iElZDB
2 - https://spark.lucko.me/qqa1NcyWfP
3- https://spark.lucko.me/GnHR5SaEU0

Modlist is also attached, the highlighted mods are the ones that are present in the server, the unhighlighted ones are just on my client. Distant Horizons is on the server because that is a functional serverside fork of the mod.
