World broke and 100% cpu tread load

Title: Tekkit server has 100% core load and slow response time

Version: 3.1.2

OS: Windows 7 64-bit

Java Version: jre7 update 9

Description of Problem:

I run a tekkit server for some weeks with no problems, but after the last two days my server responce is terible. when i type help, it takes 30 secounds or more to responce. The cpu treat load is 100% for a core. The client said, server is not reachable (in LAN). When i delete the world, the server runs normaly. How can i save my world?

In the world i have 3 Anchors. 4 cobblestone to diamond, a milk to diamond and a gravity to red matter machine. Is some one of these responsible for the 100% cpu core load?

I think this may be the same issue I'm having. Server runs fine until the first client attempts to connect. The connection goes partway before the server locks up at 100% and stops responding on the network. Telling it to stop from the console doesn't work (or works significantly slower than my patience) and thus I end up having to kill it with a Ctrl+\. I've tried disabling the anchors so far, which I would think should stop any running machines, although the first client connection may be causing a bad plugin to load. I've also yet to find anything that can scan Tekkit world files that could fix bad blocks. Virtualbox 3GB RAM 1 core VT-x running Debian nightly, Oracle JRE 7. No error messages produced.

in both cases, the most likely suspect is a block in your world doing something its not supposed to, or a block that shouldnt exist thats locking it up... etc etc etc. normally i'd suggest using mcedit to rectify that problem, but it doesnt work for tekkit worlds as far as i know. it didnt for mine but you can try it.

what you CAN try is running the world in a normal bukkit server, which will cause plenty of errors but i believe will make it either fix itself, delete all the "mod" items in the world, or at the very least make it openable in MCedit, which will allow you to find the problem and delete it.

even if it deletes all your mod items in the world, it will leave your world intact and you can rebuild off of that, to get more material that isnt vanilla you'd have to wander off to an unloaded chunk.

if that doesnt work then i dunno, mabye someone else can help.

MCedit works fine with tekkit, if you are just removing blocks. Mod blocks will show up as "unknown blocks". Adding mod blocks is where it doesn't work however.

Alright, so progress on my end. It looks like some of my player files were corrupted or something. I've had to delete two out of the four people who've tried logging in since I got it running again. I'm wondering if one of the item ID collisions might be the cause of this, although I believe my inventory had been unchanged since the last time I had logged in (mine was one of the bad user files.) It just crashed again, but just from running out of memory (is 3GB usage reasonable for 4 people being on a server at once?) Thanks for the advice so far.
