Full reinstall done, it behaves the same. This is with pure default settings. All i did was zip my world, ftp it off the vps, reinstall centOS 6 64 bit, reinstall oracle java 7 64 bit via rpm, redownload tekkit, unzip world in tekkit folder, and run it.
Still crashes funny. I'll now be deleting my technic launcher and redownloading that, in hopes that something about it is off.
edit: Brand new launcher doesn't help. New map didn't help either.
edit2: I've copied my log to the apache directory, so it can be viewed here: http://50.115.168.111/server.log
I will try to update that copy every time it crashes.
edit: Is there any way to run the tekkit server in debug mode or something to get more information when it crashes?
