MC-301664 Weakly-loaded chunks will accumulate projectiles indefinitely, causing lag or memory overflow Confirmed

Comments

This should not be considered WAI—just a few mobs standing at the edge of your simulation-distance can fire projectiles into weakly-loaded chunks, and sooner or later the game or server will lag or crash. We can definitely fix this; we need to brainstorm.
After all, you can’t guarantee every projectile stays close to you—any inadvertent movement by the player can leave those projectiles sitting in weakly-loaded chunks, where they keep piling up. Down the road, we’ll just keep getting vague reports of lag and crashes, and we’ll have to tell them, “Sorry, your game ran out of memory.
Countless players are affected by this issue without even realizing it, while malicious actors can deliberately exploit it in ways that remain virtually undetectable.
