Crafting non-vanilla items results in major crash and no new item in SMP

[DemeGeek]

Launcher Version: 0.5.4.6

Server Version: 2.1.1

Client Operating System: Windows 7

Client Java Version: 1.7.0_02-b13

Description of Problem: When attempting to craft any item from EE. IC or BC the item will pop-up in the preview box and disappear in seconds, if item is grabbed before disappearing then the client is d/c'd with the error

Connection Lost

Internal exception: java.net.SocketException: Connection reset

The error that shows up on the server is here.

I am 99% certain that what I am running is a Tekkit server so the issue shouldn't be that the server does not know the recipes and/or end items. what could be going on with it?

I have also tried to downgrade the server to 2.0 but that did not help at all.

Problem has been solved, my host needed more config before it would work correctly.
