    Can you give me a step by step runthrough on how to use this? I downloaded it, but where do i put it, and how do I run it?

    This saved our server from strange lags whenever anyone was around the bad chunks. Very simple and very effective. I wish the output wasn't as verbose and would be more denouncing on where exactly the bad chunks are so that I can easily visit the area and look for any lingering problems. We've run this 2 months ago, the issue was fixed, and nobody still have any idea where exactly the bad chunk was.

    hi i am trying to load the chunkster zip into the world file on my paid for hosting nitrious networks it says cant use the .bat files is there a way around this to get it fixed?

    If you can open jar files directly you can simply doubleclick the jar file. I assume the server is using linux and that's why bat files don't work, in that case you can just run java -jar Chunkster.jar from the shell. Otherwise it's harder because if bat files are blocked, cmd is probably blocked too. (but if that's the case, you should really look for a new host...)

    I would appreciate any help you can offer here. This is MC 1.1 on linux.

    Anyone seeing this after running Chunkster?
    FURNACE but has null. Bukkit will attempt to fix this, but there may be additional damage that we cannot recover.

    I just received this message, but still trying to figure out how to use Chunkster. I'm a noob who wants his server back!

    It's not chunkster. It's latest dev of Bukkit.

    Is there any chance of getting a Chunkster upgrade for the new map format "Anvil" which will be used in Minecraft 1.2?

    EDIT: After reading through this thread... Why do people call themselves "Admin" if they don't even have the knowledge how to make regular world backups? -.-

    The link for the latest download seems to be broken...

    Well, I basically just made a brand new folder and moved everything over. Downloaded a new R3 .jar, made a new .bat file, and ran the server. Logged in the deleted the pesky furnace. Haven't had a problem since.

    Less hate. Not everyone does scheduled backups.

    Kainzo, I'm sorry, but how can a server admin serve his players a nice playing experience without scheduled backups? I'm not talking about a backup every 3 hours or something. But a backup a day, keeps the Chunkster away. ^^

    Well, I'm using Chunkster for regular world cleanup (deleting entities and so on).

    I have a 1.1-R4 server that was crashing after a while when I tried to do a full render on my dynamic map (too many open files) - running chunkster on my map found 4 region files that crashed chunkster. after removing these region files, everything is butter.

    Of course, i'd much rather chunkster FIX the chunks, rather than just crashing on them, but at least now I know which chunks were bad. I have a copy of these 4 region files that crash chunkster, if you'd like them so you can improve the tool.

    I've been getting this error now and then. I tried chunkster and had it remove everything it gives me options for. I didn't get any errors from chunkster, but I still get this same error while the server is running.

    [INFO] [NoLagg] Removed entity '' from [world, -586, 65, -32] because it was wrongly stored in chunk [-37, -2]

    I recently started running my server on a host. While transferring my world files over via FileZilla and booting up the server, random chunks were disappearing and generating. I took this small snippet from the console. It's occurring everywhere. I tried Chunkster, but to no avail.
    25.02 07:32:15 [Server] WARNING Entity is at 318.5,-764.5 (chunk 19,-48) but was stored in chunk 24,-49

    25.02 07:32:15 [Server] INFO Chunk file at 20,-62 is in the wrong location; relocating. (Expected 20, -62, got 3, -52)
    Please help me discover whats going on! Also, I'm no Bukkit code reading pro!

    I used the chunkster from page 19, and i got this. Does this mean it worked?

    *EDIT now insteafd of java is not recognized, it says unable to access jarfile /chunkster.jar

    *Edit2 Nevermind! i have solved this by running the chunkster EXE instead of using a command line.[​IMG]

    Silly question, but is it possible to have chunkster simply check the map without fixing it? We're getting a ton of lag and the host tech support is telling me it's because of the map (no indication of this in the console whatsoever), so before I reset the map or start regenerating chunks, I'd like to make sure the guy is not full of air!

    Thanks :)

    I don't want to sound like a complete noob moron, but I have no idea where to upload the Chunkster.jar file. Many people seem to understand the instructions just fine, but I don't. Where do I put the file? In my plugin folder? And where do I run the command from - the MC client? The console? Should the server be on? Any more precise instructions for the idiots like me would be awesome...

    upload the chunkster.jar file to the folder where your worlds are stored. this is probably the same folder that contains the bukkit jar,, bukkit.yml, and whatever else. then, go to that same folder with ssh if your servers os is linux. then type in whatever commands in the instructions to check each world.

    if you're worried about what might happen to the world files, just make a copy and test chunkster on that. make sure your bukkit server is shut down before using chunkster or making a copy of a world.

    Thanks! I found a youtube tutorial to run it on my mac, it was super simple and it worked like a charm. Reuploaded the files and I think it's fine now. (Even though i was not getting any error messages, just unexplained lag... it was worth a shot. And Chunkster worked for a looooong time on the world, so it may have been a good idea anyway!)

    would like this too...

    Just so you know, I ran it this morning, and it doesn't regen anything - you don't end up with chunks cleared of builds or anything. That's what I was afraid of ;)

    hmm just want to know if my world is corrupted..

    Run it offline, then, from a backed up file. You'll see in the terminal what chunkster does; if it's corrupted, you'll probably know. Then you can choose whether you upload the "fixed" file or just keep it as is.
