Connection Problems under load

[favo]

I have a gentoo-system with vanilla kernel 2.4.22 running on an intel dual system w/ on board ethernet.

When having webserver-traffic on the server it drops all connections for some seconds several times an hour.

I've changed the http-daemon and the problem still occurs. Where can i take a look to find out why this is? Or anyone has already an idea after this brief description?

Tell me what you need to know to help me fix the problem

thx in advance for all response
