    Last night when I got home after a long night of drinking and partying, the server had rebooted all by itself.
    I turned it off and only tried to get it back up this morning....

    As soon as I ran the craftbukkit server I started getting LOADS and LOADS of errors like this one:

    2011-03-06 11:38:57 [INFO] Chunk (-24, -19) stored at (-8, -9)

    My server.log started growing exponentially...
    I tried running craftbukkit 3 or 4 times and it'll give me that error hundreds of times, non stop, filling the server.log with errors and obviously it'll crash.. not really a crash but im guessing its so many errors that it just stops showing them all...

    Does this means I lost my world when the computer rebooted?? really??
    Some help please !

    More of those lately on the forum, strange. But aside from using a backup I don't have the answer :/

    UPDATE: tried updating to latest recommended build (493) and still the same... (I was using 440 btw)

    Then stop using something that you do not understand or learn to understandit. I mean you are a server admin and you do not even know how to use a backup nor you apparently even tested it (or whether you even have one). That's not what a good serveradmin does.
    So go to crafty thread and read something or ask how to access a backup.

    @Plague : although you said it in a rather rude way, I'll take that as an advice but be careful about the way you say things ok? I'm not running a 50-100 player based server, i'm running a 5/6 friends server who's basically for fun and still in "testing phase" (we've been playing for 2 weeks or so). Loosing the current world isnt that big of a deal, I just wanna try to keep it so that we don't have to start over.

    Oh lol someone with the same issue as me, didnt see you when I looked the first time.
    You should give Plague a break, he helps everyone so I imagine it gets tiring quickly.

    A solution I found is to delete one chunk at a time from your world folder (making sure to copy them somewhere else first!) until you find the issue area, then restore every area except that one. You will lose anything in that area but it will fix your world.

    Also if you are running a backup program you should learn how to use it, or really its useless.

    I've discovered that the backups are not world backups.
    I wiped out the world and used mcedit to restore some main buildings we wanted to keep.
    Everyone's actually happy to start again, this time knowing what to do better.

    I know he helps a lot =) it's not the first time he does and I actually appreciate his work a lot !
    Props to @Plague ! :D

    Time to research on a good world backup utility !

    I had this issue myself, it's a bad chunk. How I solved it was by using Worldedit command /chunkinfo to find the bad chunk(in your case it's -8, -9). Then use MCEdit to go in and export the chunk as a schematic, then delete the chunk and then import from the previous schematic. Now in some cases the chunk was all messed up and looked nothing like it was supposed to so I had to copy the chunk from a backup file. Hope that helps.

    On linux just use cron and gzip the world folder somewhere from time to time. When you run the server in screen you can also put it offline for that.
    On windows there is the scheduler I think, but no screen for offline backup. Most archivers offer the commandline, so that also can be done.
