Error while starting tekkit server.

[yamahanytro]

I am using tekkit 2.1 for my server.

OS is CentOS

Version of java: No idea. On a VPS

When I start my server I get an id error. I have not messed with any IDs. The server was running fine this morning then all of a sudden it started erroring and not starting.
