Laggs and Crashes (Chunks Corrupting Randomly) "[WARNING] Already decorating!! Dim: 0...."

[TheDarkDeuce]

Hello everyone, I hope I can get some help here.
Im running a Tekkit Lite Server with MCPC+ 1.4.7

We have 4 Cores, 18GB Real Ram, 1 TB Space.

Whenever someone flys into an unloaded area it throws this when creating the chunk sometimes:

This causes laggs and it appeared since I reinstalled the server and put the world and plugins from 11.15.2014 to it.

What version/build of MCPC+ for 1.4.7 are you using? Not that one anecdotal reference means much, but I've been running TekkitLite on the latest (L67 & L70) for 18+ months and have never seen this.

I have mcpc-plus-legacy-L67.jar
