Title: Unknown Error - Server Crash

Version: 3.0.3/3.0.4 - forestry installed.

OS: Linux Server, Mac OSX Lion Clients

Java Version: 7

Description of Problem:

My mates and I were just starting out in our new server, when unknown, unexpected errors caused us to randomly kicked.

It also appeared when we used stone axes to cut down some trees.

I would really like someone to help me ASAP as the players are nagging me to fix it.
