I am trying to runn a private server of the Aether II and having problems. I have installed everything correctly with Forge and API and put Aether II v1.0.2 in the mods folder. We can connect and go into the Aether just fine but we get random lag spikes that kick the server offline or just an individual player. I am hosting the server with Minecraft.net with 10 slots and 1024 MB of RAM. 

Here is the expections that are being thrown in the conole hopefully someone can make sense of it...
