Tekkit Server Java Errors

[Slicerm1]

Hi, me and my friend have been trying to start a tekkit server for 2 days now and we keep getting java errors. Recently I have tried uninstalling java and downgrading it to previous versions. I'm now using java 7u21 (64bit) now and am still getting the errors. We are using the recommended version of tekkit and download the server from the official modpacks. When my friend tries to join my server or i try to join his we fall through the ground and then after 30 seconds it will kick us out giving us a java error. The one I have gotten recently was Java.net.socketexception: connection reset. I attached the launcher cmd which shows all the warnings in it. Im running a 64bit operating system with 8gigs of ram and on the server I have its max amount of ram set to 3gigs and least to 2gigs. If anyone knows how to fix this problem I have been having that would be great.
