server cpu running at 271%

so we are running a bukkit server and we where hit with a hacker and bot we banned them but they brought the server down and when we brought it back up but now the server is running at 271% of the server we turned off all plugins and it dropped to 220% but we need help we've tried everything we could think of but no luck and the hackers are still trying to get on but being disconnected from the server as soon as they try to get on.

Download the latest version of bukkit, and did you make sure you put the correct java code into RUN.bat?

we changed the ip and it fixed the issue but we cant make it make it go live because we dont want to buy a new ip

 

Try to reboot your router

 

I have the same problem =/

Our bukkit version: git-Bukkit-1.2.5-R4.0-b2222jnks (MC: 1.2.5) (Implementing API version 1.2.5-R4.0)
CPU Usage: ~ 200% ( ???) (ps aux | grep java)
After restart a short while about 350% than it drops to about 200%.
Hardware: Intel Core i7 CPU 920 @ 2.67GHz , 8 cores with 8 GB RAM.
Software:

Code:

Linux Debian-60-squeeze-64-LAMP 3.3.6-al3xst-1000mhz-v0.1 #1 SMP PREEMPT Mon May 14 11:52:33 CEST 2012 x86_64 GNU/Linux
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

Code in startscript:
java -Xmx1024M -Xms1024M -jar craftbukkit.jar

I tested the server with and without any plugins. But I get the same CPU-Usage.

 

thats because of the lape second. you must set the right server time on linux. google it there are already some fixes for that
see here http://www.minecraftforum.net/topic/1322720-extremely-high-cpu-usage/

 

oh wow
thanks^^
