Very interesting point.
- do you think this could hurt my server's stability too? (most of its work is a noticeable amount of packet-forwarding, and other network services, like firewall, dhcp server, ntp server, etc)
- if so, in what conditions? can I do something to prevent this? or should I just get rid of the swap partition?

- does swap partition do any good for me at all? I mean if we even suppose nothing bad happens because of it, is it worth risking to keep it? 

thank you.
