This took several weeks of leaving my server running before it created a noticeable problem, but my bee area was causing a ton of lag, and after some troubleshooting (thanks Opis), I discovered that two chunks were packed full of thousands of "Small Fireball" entities all at about y=127. I flew up to take a look, but nothing was visible. I used MCEdit to clear the entities, which greatly improved my FPS, but I'm wondering if there's a way to keep this from happening again in the future. Other than just not using Volcanic Bees anymore I mean.
