Thanks goes to:

Vjay Larosa, David Harrington and Bill and Steve.

My original two posts are below.

The problem turned out to be a dual ip-adress, I had a lot of trouble tracking
this down as the machine with the offending ip was on a different vlan.
This ment that I could never ping the ip-adress from the "real" network, it
however managed to push it's mac-adress into the routers arp-table.
