This is the output for "netstat -an", as you can see it repeats every time you find a LISTEN for the lighttpd server

(and it keeps repeating... I think you got the idea) |
I wasn't able to find something wrong on it.
We have other servers with the same setup as this and this is the only one that fails like this.
I've already tried removing and re-emerging net-tools, with no change on the output.
I've also tried updating the kernel with no different results.
Also tried rebooting it to check if it wasn't some memory cache issue, but it's still there, although when it starts it doesn't have this issue, it's after I turn on the lighttpd that it starts to loop eternally.
This is some other useful data:

BTW, I've said "almost" infinitely, since a count actually told me a finite value... but some big kind of unreal one.
~ # netstat -an | wc -l
2106947
On a different server with the same setup, and on the same round-robbin setup, the result is really more acceptable:
~ # netstat -an | wc -l
28626

It got fixed by running an emerge -DNuv system, updating to the kernel 3.0.3 and doing a final reboot to load it
