Q:

Debian server seems to use more and more swap

I've got a problem with my debian server. It has 4GB of ram and 1GB swap. Swap is around 95% full and ram still has 80% left. I'm running lighttpd (max 40 users at the same time) and some gameservers (VALVe games) on it. Any ideas?

A:

Have you run top on your server to check what is using the swap space? A more in-depth alternative is htop.
