I started to use Icecast2 on Ubuntu 8.04, after 200 connections (more or less) it stops working.
Kernel says something like SYN flooding, using cookies.
It's like the system somehow stops connections.
The pc has 8 core and huge internet connectivity so that's not the problem. Icecast conf is the same I used on a Win2003 and there it worked perfectly till 800 connections.
Surely I'm too noob to understand the problem.

Any help very very very appreciated (I dont want to go back to Windowz!!!)
