Issue description:

Server crashes when I request autocraft of high amount of IC2 overclockers. It also crashed when someone on server autocrafted planks? It crashes as soon as you press the button after typing how many you want. (Pre-calculation screen).

Interestingly it only happens on the dedicated server. It has 10GB ram available so I don't really know.

What happens:

What you expected to happen:

It would go on the calculation screen and we can click start.

Steps to reproduce:

1. Craft many items on a server.
2. Watch it burn.
