This warning causes the server lag and Crash

I do not know, but causes it to be lag and disconnection of players

Need more information.
Start by making sure you have the latest version of Java

It might be occuring on line 4155 in your worldguard con
I'm pretty sure worldguard does't have 4155 lines of config unless you accidentally pasted something in it. Try fixing the last issue for a successful hook by IceControlPvP.

Code:

[18:54:04] [Server thread/ERROR]: Config file plugins/VirtualChest/Chests/Rusadoxx.chestYml isn't valid! Can't construct a java object for tag:yaml.org,2002:com.aranai.virtualchest.; exception=Class not found: com.aranai.virtualchest.

I'm not entirely familiar with this plugin, however it looks to be another yml config issue. Make sure you're not using any tabs in your config.yml files. If you're using a text editor other than notepad, make sure it isn't automatically putting tabs in your config file for you while editing.

Code:

[18:54:05] [Netty IO #11/ERROR]: Could not pass event ServerListPingEvent to AdvancedMotd v1.0
 
org.bukkit.event.EventException

Please update AdvancedMotd and your craftbukkit build. If this problem still persists, make sure you have your config set properly. Then contact the author if problems still continue.

WGBlocokRestrictor config error. This might all be directing to your one config file for WorldGuard, as it keeps referencing a colon, but I would have to look for myself to be sure. Make sure you're writing config files properly and these types of issues should go away.
