Server doesn't save automaticaly (even with /save-on)

I Have huge problem, every time before i stop the server I need to say /save-all. Accidently I clicked [X] button on a terminal and later i found the server as it was after the last /save-all.

OS: Debian Wheezy amd64

Code:

Linux alexhr2000desk 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux
java version "1.7.0_03"
OpenJDK Runtime Environment (IcedTea7 2.1.7) (7u3-2.1.7-1)
OpenJDK 64-Bit Server VM (build 22.0-b10, mixed mode)

Java version: java version "1.7.0_03"
No wrappers used...
Command used to run the server:

Code:

java -Xms1024M -Xmx1024M -jar craftbukkit.jar

Plugins: WorldEdit, iConomy, CommandBook, mcore, vampire, Vault, ProtocolLib, Multiverse-Core, TerrainControl, WorldGuard, DisguiseCraft, Multiverse-Inventories, Turnstile, CraftBook, BKCommonLib, Train Carts
No errors shown.
Oh... The Craftbukkit version is 1.5.2-R1.0

 

Always stop your server with /stop. It will save everything before shutting down.
