Extreme Lag with a new error.

I am getting EXTREME server lag for no reason now and the only error I seem to have is this.

2011-05-19 04:41:11 [INFO] Starting Minequery server on *:25567

I included the minequery line in case it is just a minequery problem

I do have the piston mod so that might be it... no other errors that point to lag but starting a new map with bukkit and no plugins = no lag

Well, what happens when you remove just the piston mod?

 

It still lagged. I found the problem.... 43,000 entities were loaded
