java.net.SocketException: Socket closed - Help

Recently my server has been randomly kicking everyone (except myself) and I have to reload the server to allow people back in. The error I get is:

Code:

14:00:07 [SEVERE] java.net.SocketException: Socket closed
14:00:07 [SEVERE]     at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:116)
14:00:07 [SEVERE]     at java.net.SocketOutputStream.write(SocketOutputStream.java:153)
14:00:07 [SEVERE]     at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:82)
14:00:07 [SEVERE]     at java.io.BufferedOutputStream.flush(BufferedOutputStream.java:140)

14:00:07 [SEVERE]     at net.minecraft.server.NetworkWriterThread.run(SourceFile:116)

When people get kicked they get a "java.net.socketexception: connection reset". What is causing this? How do I fix it?

 

bump

 

I'm getting an error like this for some people too.

 

Im getting this problem too (and sorry for the bump but i dont want to spam the forums with something already here)

how do i fix it? is there a way to increase the timing?

 

I have the same error
Bukkit #1000
12gb DDR3 ram (9gb for mc)
I am generating no errors on server startup but 20 seconds after joining, the chat stops responding, then I goto the console type somejibberish (ksdhfakd) but no response (no "unreconized command") then I close the server console start it back up only to repeat, what is happening?!

 

Bump

 

i get the same errors, but i dont need to restart the server
for me:
its just lagg problem, connection gets interupted for a moment causing to lose connection for players, happens to me most of the time when my server is full

 

I get the same error, anyone find a fix for this?

 

ditto

recenty used chunkster and i made a new world and it now works so ya i guess its world corruption or something but im not shure so take this with a grain of salf please.
