That's an error in bukkit, not craftbook. If you update spigot to the latest it has been fixed.

Actually, it isn't fixed in Spigot. If you use this jar http://files.krinsoft.net/main/java/craftbukkit-dev.jar, It may be fixed.

Link isnt working. Also was doing some more testing and found the issue to be something to do with craftbook and worldguard and block-zombie-door-destruction: true

When true craftbook will throw this massive error and inject mass amounts of false entities and overloading RAM and CPU Dropping TPS to a crawl. If block-zombie-door-destruction: false then zombies break down doors and it seems everything is fine.

Unable to test your craftbukkit build as the link doesnt work.

Used the jar from your PM on bukkitdev and the error continues when villagers go in and out of doors. To reproduce this try spawning 50+ villagers in a area where 100+ doors/buildings are located (villager farm), leave the area to have the chunks unload and the error will occur and spit out 5000+ entities that continue to grow and unable to /killall or /butcher or /remove.

Using you craftbukkit build i have been able to reproduce the error over and over again with steps provided above. Disregard the zombie block door thing. The issue is when many villagers attempt to enter doors at the same time VehicleEnterEvent.

More info. Can reproduce using villager eggs or using /mod villager command in game.

But it is a bukkit bug. Also that error has nothing to do with villagers. Villagers do not call VehicleEnterEvent when opening a door. If they do, it's a bukkit bug.

I have posted an error report on the bukkit issue tracker, hopefully they can solve this issue.
