Hi, hope someone can help me.
FTB Launcher version: Rec. / Mindcrack
Minecraft Version: 1.4.7
Java version: newest
Detailed description of the issue / how can the issue be recreated:
Randomly i get disconnected from my server with [Internal Server Error]. I have no idea, why this happens. I'm in a Minecraft server cloud. The server has 1 GB RAM, I'm the only one wo playing on this server, at the moment the map is complete vanilla, means, no machines etc. are placed. I'm using the Thaumcraft Axe to fell trees or flying in that moment, when the error occurs.
Error logs:

Presumably the server continues running after you disconnect?

I suspect this might be something wrong client side. Can you post the console logs from the FTB Launcher to Pastebin for us to take a look?
