Server crash with BuildCraft liquid transport pipes

Title: Server crash with BuildCraft liquid transport pipes

Version: 3.1.2

OS: Linux Debian x64

Java Version: Oracle 7u10

Description of Problem:

Hi,

This error appears one or two times by day.

When this error occurs, the server still running, but, all players are kicked and can't reconnect.

I can't reproduce this error on my test server.

If i read logs, i think this error occurs when a player teleport near liquid transport pipes (like pumps or engines).

at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:819)

 at java.util.ArrayList$Itr.next(ArrayList.java:791)

Seems to be an inter-thread error, but, i don't know Java anymore...



Can you help me ?



Thanks.



PS : Is very difficult to speak english for me.

Up, please !

What do you mean by "when a player teleport near liquid transport pipes".

Do you mean with enderpearls, commands or what?

Sorry, i don't seen your reply.

Since we have forbidden BuildCraft Waterproof Pipes... We don't find any other way to resolve this error.

The error was occur, when players type /back, /home (Essentials for Tekkit) or when it was staying near pipes (rarely).
