Title: Tekkit server Startup fail

Version: 3.1.2

OS: Mac OSX

Java Version: Unknown

Description of Problem:

Me and my friend were playing my tekkit server for awhile and out of nowhere it crashed, every time i tried to restart the server it gives the same error message, i deleted everything except the world and the plugins folder but the same error message occurred. The only plugins i have in my folder after i deleted most of them, is mob arena, the default CCplugin, all the essentials plugins, and worldedit. STILL the same message, i left it alone overnight, still same error, so then i just came here to answer my problem. 1 more thing, im running a tekkit 3.1.3 server. PLEASE help i really don't want to delete my world or anything but if i have to ill do it.

Okay, so i moves the 3 world files (overworld,nether,end) out of the folder for it to regenerate and it turned out the world was the problem, ill just put my house in a schematic, but can anyone tell me if theres a certain block or something doing it?

You need to delete the Buildcraft API in Railcraft, I think.

Alright i just did something else, i downgraded to 3.1.2 and buildcraft now works, just a notcie for others who read this but i couldnt use any pipes in buildcraft or 2nd gen machines from IC2 (such as rotary macerator) in a tekkit 3.1.3 server but 3.1.2 still works fine , and thanks for all your suggestions

Or you could use the fixes from this thread and enjoy updated mods:
