Title: Loosing Ticks with Time

Version: 3.1.2

OS: debian-6.0.4-amd64 Fully Updated

Java Version: build 1.7.0_05-b06

Description of Problem:

The Tekkit Server runs with 20 Ticks just after he starts. But with the Time the Server is running empty i'm loosing Ticks. Now after 6h the Server is down on 3.4 Ticks.

Server is on 100% CPU

I tried the Following Things:

Running with no Plugins (Still 100% CPU)

Removed all World Anchors (Still 100% CPU)

Stopped Every Factory on the Server (Still 100% CPU)

Map Size: 6000 Blocks Radius. (2 GB Big)

CPU :Intel® Xeon® E3-1245 Quad-Core Hyper-Threading-Technologie

RAM i give Tekkit.jar : 8GB

Amount of Players Online: 5-10

When Players Join it speed up the Loosing of Ticks.

Server worked Perfectly like 2 Weeks ago. I didn't change anything since then.

Server:

CPU:

Intel® Xeon® E3-1245 Quad-Core

inkl. Hyper-Threading-Technologie

RAM:

32 GB ECC RAM

Hard Drives

2 x 3 TB SATA 6 Gb/s HDD

7200 rpm (Software-RAID 1)

Network

Traffic

Unlimited*

What can i do against this?

//edit:

I Reduced the Map Size to 3000 it's not as worse as before but it still happens to 3-4 TPS but not as fast as before.
