CRAFTBOOK-2817 - Reported by robotnik

Hi, when I clicked a sign my server crashed and shut itself down. Here are the errors from the console log

Using bukkit 1.7.2 R0.2 Beta
Using CraftBook v3.8b1

That's a PermGen error, meaning it's not due to craftbook, but the server running out of PermGen space due to 1.7.
To fix it, either enable permgen garbage collection or increase PermGen space.
