Communication error

The server worked fine for a while then suddenly it started freezing things (eg. killing a cow), then I get "communication error" when I try to sign in again.

I've had this problem before and I thought my world got corrupted but this happened again now when I made a completely new server. Why does this happen?

This must be some really unknown problem when no one knows anything

Any guesses?

This happens to me too, and has is happening to several servers. I have yet to see an answer to this.

 

Does anyone have an idea on what is causing this?

 

Very likely to be a plugin issue. Start removing plugins and test.

 

With a clean Bukkit install, the message is gone. This is Pre-release 5 b 14.

 

@Loathsome - see above.

Do you think 1GB of ram is enough to host a Minecraft 1.9 server?
I don't think so.
Also, you might want to
- download Java 7, x64 VERSION!
- change your maximum RAM to AT LEAST 2GB (changed it for you in the script below)
- change your startup script to point to this java version (if you don't change anything, it should probably be similar to this: )

Code:

@ECHO OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"C:\Program Files\Java\jre7\bin\java.exe" -Xincgc -Xmx2G -jar craftbukkit-0.0.1-SNAPSHOT.jar

Found out the problem. It was a plugin problem.

Choptree is a plugin that let you chop down trees like cactus. This causes a lot of saplings and wood getting stuck in the trees that get forgotten. Eventually these items pile up in huge amounts = causes the server to lag and eventually make it overloaded.

So if there is a plugin that cleans up items when there's too many laying around, this plugin would still be usable.

 

You really, really should bring this up with the plugin dev. It should be something they fix in their code.

 

Could it be your Static Ip has changed?
