Does anyone know how to fix this server crash?

[Kirbinator]

I have been recently trying to create a Craftbukkit MC Port Central Tekkit Classic Minecraft Server on my computer and It was a success; no crashes, no console errors and etc. When I uploaded my server files to my ftp database and then ran my server, My server crashed. Would anyone know how to avoid this specified server crash in the future? Here is my console log:
