What happened?

Server is consistently crashing after loading a specific map area where a player base is located, reason seems to be ticks taking longer than two minutes to process.

I tried diagnosing with spark but it doesn't help much since the server literally stops (up until it crashes) when the issue happens so spark is unable to record anything and the only thing that it reports is:

[spark-async-sampler-worker-thread/WARN] [spark/]: Timed out waiting for world statistics

After some fighting with JFR I tracked down what I think the cause was, a massive amount of Evil Spirits, likely spawned by EvilCraft when mobs die to the MobGrindingUtils mob masher. Sadly running /kill @e[type=!player] only results in 200 entities killed and it only works when the relevant chunks are unloaded, because as soon as the chunks load the server instantly crashes.

Removing the mod yielded a lot of lines in the console when the chunks loaded about the entity missing and so far everything has been fine however this has only been with me in the game, I will wait for the other players to rejoin.

This started to my server also after using ftb chunks to chunkload areas. After removing all claims the timeouts stopped
