    posted a message on Internal exception: io.netty.handler.timeout.readTimeoutexception
    In my case the server is running on an old computer too and the memory is almost always close to 100% usage. However this never presented a problem (or at least I never assumed it had something to do with the error), and I even resolved the issue deleting the player file causing the problem as I posted couple of messages above. The thing with the memory started after the horse update, now that I remember.

    posted a message on Internal exception: io.netty.handler.timeout.readTimeoutexception
    Ok, I run a server with Multicraft and have been suffering the same error and of course my players too.

    Here's what I found, and what worked for me. I noticed that the error popped on my face whenever certain player was trying to login. Everytime he entered the server, he got a "Internal server error" message, and everyone else trying to log in got the infamous io.netty error. People inside the server got kicked with io.netty too, and the server was no longer accepting any player. The Multicraft panel showed every player that tried to enter, like if they were still inside playing, only there was nobody inside. After a server restart, everything back to normal UNTIL this player tries to log in again, and all the ritual repeats on. I tried Region-Fixer to check the integrity of the files and the world, but it reported no problems whatsoever, not even a single corrupted chunk, nor player files.

    What I did was I deleted the .dat file belonging to the player causing the issue (it's located inside the world folder in the server, and it's named after the player, for example my file was Liederkranz.dat). By deleting that file, the server had to create a new one when the player logged in. Obviously he spawned in the spawn point with an empty inventory, a fresh start. That solved my problem. So far, so good. I hope this helps.

    Quote from chuckaknuckle

    That can happen if the server crashes while in the middle of saving a chunk.

    You might look here to see if there are any solutions: http://mcsaver.net/


    Thanks a lot chucka for the quick reply. Yes, I thought it could be something like that. But even so, the server keeps hanging up at random times varying between 30 min and 2 hours. Even if I manage to save the world (heh, angel chorus here) it'd be pointless with the crashing still happening.

    I will give it a try anyways :smile.gif:.

    posted a message on MC Server crash / hangup
    Hi there MC gurus.

    Before anything: I'm running a SMP server on a dedicated machine. This is a Pentium 4 3Ghz, 2GB RAM running Win XP. No antivirus, no firewall, no any other program than MC server. It's in the same room as my personal machine, but due to the reduced space and not having another moni, keyb and mouse I access it via remote desktop.

    The server is plain vanilla and the world only weights 12.8 MB since it's almost brand new.

    The problem is, after it've been running for a while (maybe 30 minutes, maybe 2 hours) it simply hangs up, closing the remote desktop connection, not responding to pings and not being accessible via Win Explorer to see the files. It's like it's off, but the PC keeps on.

    After rebooting and restarting the world, in the best case scenario I get this:

    If I stop the server from the console and restart it, if I'm lucky it "fixes" the java.io.IOException errors and the console displays the normal startup. The problem is that I eventually get some things messed up in the world, like ice growing in places where there was water before.

    In the worst case scenario, when rebooting after the hangup, the world gets totally screwed, not being able even to start and leaving the console full of errors (I didn't log theese, I will next time it hapens).

    I'm a person who makes backups often, however because of this issue many times players have to build twice the same things because I keep rolling back to the backup.

    I thought it was my hardware, since the PC is rather old and was my previous PC before buying the actual one, but I doubt it. I'm leaving it on without running the server to see if it hangs up the same way. So far so good.

    Any ideas? If I'm missing something or you guys need more info that I might have overlooked just let me know.

    Oh, and let me show you something curious that happened because of the mentioned hangup in my previous world (now long gone due to extreme messup because of that). Just before the world renders unplayable, we got this... pigs ahoy!

    Any way to make my character look at the camera while in 3rd person view? Before 1.3 it was with F1 (holding it down) but now just disables the hud without changing the camera orientation.

    Perhaps there's another way I'm not aware of?

    what exactly is a seed?


    AFAIK, it's some sort of "generation code", like... unique for each world. I think it's meant to share worlds without having to pass the save files between people.

    Whats this? I dont remember ever seeing these in the texture.png file????

    the gray one under obsidian is leaves. they are colored in game based on the biome. The other one is new to me.

    Oh yeah I forgot they did that with Leaves and Grass.

    But yeah, I have never seen this block before. I know it is not in game (Or at least not discovered) and I know I have never seen it in the terrain file before : \


    New ore? Maybe because of how much of a dissapointment Lapis was?


    Notch: Today we are adding a new ore to Minecraft, its going to be rarer then Diamond!
    Community: Cool! What can you do with it?
    Notch: Its dye! Because I know how much all you guys like Dye!
    Community : :\


    I had the sensation it's lapis lazuli ore, and checked the Minepedia. It is. Or at least it says so. When mined drops lapis lazuli dye to make wool blue.

    EDIT: Ok I checked again, it's a mix between Obsidian and Lapis :S.
    My mistake, I'm as lost as you guys. :tongue.gif:

    Well, good and bad news. As in every case similar to this, the Windows binary package of the program isn't up to date with the source version.

    The good news is that the error got fixed in a later version for which there isn't an exe package yet, so the bad news is that I'll have to install Python, PIL and Numpy in my server and use the latest source version. Another solution would be to remove the corrupt chunks generating the error, but my head starts aching just by thinking about doing that.

    Interesting... That works.

    I've rendered the chunks however I believe I'm receiving an error:
    Trackback <most recent call last>:
    File "Chunk.pyc"
    .....
    ...Several files are listed
    .....
    IOError: Not a gzipped file

    What the heck is going on? I'm not receiving an files into my cache directory nor any testdirectory/world directory....

    Any thoughts?


    Same as above, I get the same error. Maybe we're missing something? I'm running a server with hey0's mod on WinXP32.

    Below is the output I get, hope it helps. What I observe is that some chunks are rendered ok but at some point it encounters invalid files (not gzipped) and stops. The tiles are generated in my designated cache folder but obviously the final map with the index.html is never generated. It's like some files of the world are gzipped and some others aren't. I thought about "gzipping" the ones with the error, but as all of us know, the world folder is an endless trees of subfolders.

    As a test, I tried to render one of my single player maps (about 1000 chunks) and it ran flawlessly, generated everything and stuff.

    hey0, I just love your server mod! I have a couple of questions about two of the last builds:
    Quote from OP »
    Build 118

    * Added Mob.getX/Y/Z/Health, Mob.setX/Y/Z/Health
    * Validation for /spawnmob and /setwarp

    I'm a complete noob in terms of Java, what exactly does the first line mean? The first thing I thought is the bless of killable mobs or at least an approach to what it would be in a future, but since it's still serverside I had my doubts.

    And:
    Quote from OP »
    Build 119

    * Added block data.
    * Added mob.getName() and mob.dropLoot() (Automagically drops loot if health is set to 0).
    * Added server version stuff. (/version in-game version in-console).
    * Removed backwards compatibility for old plugins.

    About the second line, didn't mobs already behave that way in the first place? I mean, dropping loot when killed with fire or so?
    About the /version command, I couldn't get it to work, neither from the console, nor from the game (I'm currently running Build 120 with latest Cuboid Plugin, perhaps it's fixed in Build 121).

    Well, thanks in advance!!

    No problem. As I mentioned you do NOT need to install Python or anything else. Go to the Minecraft-Overviewer website and click on the button that says downloads. Now download and unzip the package labeled 0.0.3 or something like that. For simplicity's sake I also copied my "World1" folder (or whichever world you want) into the same directory as the Overviewer, although this might not be necessary.

    Open a command prompt in Windows (open your Start menu and type "command prompt") and navigate to the Overviewer directory that you just unzipped. You can do this using the "cd" and "dir" commands that you can figure out on your own. Your location will probably be different than mine.

    Now in your command prompt, type "gmap 1 testdirectory" and it should begin processing. Replace 1 with your world number and testdirectory with the name you want for your output directory. That's it, you're done. If you want to add options just look at the list on the webpage or run "gmap" with no parameters.

    Maybe the author will update the instructions on the website at some point to be a little clearer.


    Are you sure I can just run gmap from the CLI without having Python installed? I tried and (not surprisingly) "gmap" wasn't recognized as a command.

    Right now I cannot install Python in this machine to give it a test but I will from home. However, I'd like to know if there's an executable or standalone version of this, so that you just run it from the command line in Windows.
