    Do you know how to run a bukkit server evenly across all my cpu cores equally.
    Anyone know how to set java up to do that?

    You're using Hamachi. Others who wish to join your server also have to use Hamachi too.

    Yes, I know. They do
    If I want to join their server I can. They also don't know the problem

    They need to fill out the correct information for your Hamachi network, including using the right IP and PW.

    No, I can join the server but my friends can't and it doesn't give errors
    But when I open the server with CraftBukkit Starter it only opens the cmd, my friends says there need to open 2 things

    I haven't seen a way to do this. Bukkit is designed to be multi-threaded, and therefore, multi-core, but plugins (such as worldedit) have to follow suit to do costly computations in seperate threads to avoid freezing the server.

    You would find a bigger performance boost by moving your world files to a ramdisk (if possible). If you do, make sure to make a script that takes regular backups.

    @Zectric
    As the error states, Java has run out of memory. This can be prevented somewhat by the use of switches when starting up bukkit. We could look over what might be causing the problem if you post your server startup script.

    @MagikarpLOL123
    Which permissions plugin are you using? Permissions 3.x?

    Switch to PEX if possible.

    Looks like a plugin incompatability. Are you running Essentials?

    Try to do it without hamachi.

    u will need some form of permissions plugin. that way u can allow/deny players to do things from plugins to building.

    you can try this" http://forums.bukkit.org/threads/mech-admin-mobiile-the-mob-entidex-v1-1-control-mob-spawn-860.7773/
    idk if it will work against 1337 or watever the newest rb is...
    jk that just limits where mobs spawn...i could make you a a plugin for it but it would probably cause a significant increase in lag.


    did @Pencil get banned? i haven't seen any of his trolling lately :( he almost has as many infractions as you Mr. Man!

    Hello consulting group ! :) I don't know if I can ask my question here.

    I'm building a community for minecraft and me and my staff have a big problem...

    We have about 6 worlds.
    We want only PVP and Mobs/Animals on the world called PVP for others no pvp, no animals, no mobs.

    Is there a plugin to do that ? I did a lot a research but nothing worked pretty well.

    Thank you very much in advance !

    1. What plugins are you running?
    2. What is the size of your world
    3. Are you hosting at home or renting from a VPS.
    Alternatively, you can check this out,

    http://forums.bukkit.org/threads/mech-edit-ptweaks-v1-6-remove-all-server-lag-1317.39399/

    Try this;
    http://forums.bukkit.org/threads/tp-multiworld-v1-9-0-the-easy-multi-world-plugin-1317.35521/

    You'll need a multi-world plugin, and probably some other stuff,

    • World Guard & World Edit

    With 3MB upload speed, you should be Fine hosting 3/4 players on.

    Your Java.exe should be using resources, when you hit task manager, what's your starting command for the server?
    Also, did you try right clicking on the process in task manager and setting priority to high?

    1:
    CommandBook, ServerSave, Ptweaks, CreativeGates, WorldEdit, MobDisguise, PlgSetspawn, MultiHome, Prefixer.
    2:
    I just started a new one today, its 2.83 MB. This problem also occured before.
    3:
    Home with Hamachi.

    I'd like to say, that this problem started to occure some days before this. Suddenly the server just started to lagg.

    1. There may be an error, you just need to catch it.
    2. You can try a new server running command; http://forums.bukkit.org/threads/assigning-more-ram-to-a-server-guide.1432/
    3. You should update your plugins (i.e. iConomy 5->6)
    4. You can try re-installing Java.
    5. It could be one of your plugin's giving your server a hard time, after <x> amount of time, thus why RAM fluctuations and perhaps server "dying"

    I'm not familiar with Hamachi, what's your Operating System your using? If your hosting from home, what's your down/upload speed?

    www.SpeedTest.net

    also you could try one of these commands;

    Okay, so you have 3 MB upload speed. What's the average user you have on?
    W7 user's a lot of resources, that is very tedious, just as "For your Information :)"

    I mostly have 3/4 players on :p Note: This also happens when i DON'T have players on.
    And, the server ( java.exe ) don't use any CPU.
