Did you tamper with the craftbukkit.jar file or your world file? That might be your problem... other than that, I don't know what's wrong.

 

Hmm. I get this error to.
I use bukkit build #740 and run it on Fedora...
Hardware is xenon 3.2 x 2 cpu, 32gb ram, 2x scsi 1tb raid. with online only 40 players

ps: sorry for my bad English....

 

Yeah. I was using 760 with that error. Are you currently using PerformanceTweaks and/or MultiVerse?

Also i hope someone knows what causes this.

 

Bump

 

how can i post a thread xd im getting chunk errors and i need help really bad

 

What kind of chunk errors are you getting? Can you post an example? I can probably help with that.

 

I had that issue a while ago, sorted out outdated plugins and everything was fine again

 

ok these are the chunk errors that keep spamming every second lol:

betw i have a mac osx version 10.6.7 processor: 2.4 ghz intel core 2 duo memory: 2gb 1067 mhz DDr3 hope you can help me

 

What plugins did you update?

 

Urgh I doubt it was anything specific, I just simply went through and checked if there was a update for every single plugin i had installed, then if there wasn't 1 i'd check the last 2 pages to see if other people were reporting errors

 

Tis fairly simple to solve. You will have to get familiar with Chunkster.

Hope it works!

Thanks, i will do that now

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Haha, have fun If your having like 25 plugins like me that can be a pain Anyways, it might just be the cause, so you will still have to use some chunk repairing thing.

 

Nothing wrong with my chunks, i fixed that a while ago with Chunkster Just the darn read error xD

 

Alright Then hopefully that will be fixed soon
