Getting a server overloaded message when i join specific world

Hi, so alot of people on my server wanted a creative world, so i made one using cleanroomgenerator. It's a very simple world flat only 25 blocks tall and no entities or weather. For some reason whenever i go into this world it spams my terminal with [WARNING] Can't keep up! Did the system time change, or is the server overloaded? This is my 5th world including the nether and the end worlds and my ram is no where close to overloading. What could be causeing this? It spams the message about every 5-10 seconds and it only happens when i teleport to this specific world.

 

This isn't memory related. This is CPU related. Check the CPU when you teleport to that world. It will probably spike to 100% or something like that.

 

do you know why? it jumps from 12% to 100% when i join that world?

 

It can be lots of stuff. But I'm no server administrator. You could ask the Bukkit Consulting Firm. They give very fast responses too!

Also, a list of your current plugins would be nice. Maybe one of the plugins is spiking the cpu.
