LD and Zone disconnects
 

I am having a very weird issue. Server has 2 gb of ram. I am running 1 static zone and 7 dynamic. If more than 3 players enter a dynamic zone people will go LD or the zone seems to disconnect from the world. The toons can still run around but mobs stops responding you can't cast spells and commands like #zonestatus don't' work.

The server has almost 1 gb of free ram when everything is running

Anyone experience this before of have any idea how to fix it?
