Extremely High CPU Usage

    A few days ago, my server started using a ton of CPU. It was around when I upgraded to build 803. My server with nobody in it uses 80% of the CPU, and when there is one player playing, it goes up to 95%-100%. I know it is not any of my plugins, as when I remove all of them it still is that laggy, and I know it isn't my Bukkit GUI 'Crafty' as I ran it without it and it still lagged. I'm running Windows 7 Home Premium, the architecture is x86, and my version of Java is 1.6.0_25. I am not running any wrappers and my build, as I have stated, is 803.

    The command to run Bukkit with Crafty is as follows:
    Code:
    @echo off
    set PATH=%PATH%;c:\Program Files (x86)\Java\jre6\bin
    start /b javaw -Xincgc -Xmx1G -jar crafty.jar
    Without the GUI it is like this:
    Code:
    @ECHO OFF
    SET BINDIR=%~dp0
    CD /D "%BINDIR%"
    "%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit.jar
    PAUSE
    My plugins are as follows:
    • Appleseed
    • AuthMe
    • BinaryBlood
    • bukkitPiston
    • DefaultCommands
    • dontkickme
    • EasyRules
    • ecoCreature
    • EggRenade
    • GriefAlertR
    • HeroicDeath
    • iConomy
    • LWC
    • mcMMO
    • NagaLightningCake
    • obuJustShutTheHellUp
    • OpenInv
    • Permissions
    • PortalStick
    • Reporter
    • runecraft2.6.1
    • Stargate
    • ThunderTools
    • Tombstone
    • WorldEdit
    • WorldGuard
    As I have said, I do not think any of these are causing problems as it is laggy without them running.
    I am not getting many warnings, but the most common warnings are Can't keep ups, Connection Resets, and Bad Packet IDs.
    What I have tried has already been listed.

    Any and all help is appreciated!

    tl;dr: My server uses too much CPU. It isn't my plugins. Pl0x help.

    Yes I downgraded to 1.5. Server lags a lot, when you join the server you just fall; I can't do anything while its running... I have no idea why!

    I suggest just waiting to Next recommended build comes out. Also downgrading can be dodgy. FYI

    It started before I upgraded to 1.6, just when 803 came out, a day later, it started lagging

    Does it happen without any plugins?

    Try with a new map. Wait until it loads some chunks around and test if it continues at 100% core load.

    Woah. When it generated a new map and I used that, it was completely lagless! Trying with all plugins now...

    With the plugins it worked fine too! Must have been the map... Now to find a way to restore my old one...

    Hmm... I've got an idea... what if I converted it into single player and then changed it back...


    EDIT: It appears that a file in my region folder is 'r.-12.-4.mcr', while all the others are close to 0. I'll delete the file and see what happens.


    Nothing happened.

    May help!

    Heres a server upgrade if you want that: http://ci.bukkit.org/job/dev-CraftBukkit/812/

    This is build #812, it has some bugs... (1.6.4) But if you find the bugs and then send it into bug report, then you will help the Bukkit team on the latest Builds! :)
