Are you sure your kernel sends out gratuitous ARP every 5 mins? As my 
memory recalls me Solaris purges unsolicited ARP entries every 5 minutes 
and solicited ARP entries every 20 minutes. But gratuitous ARP requests 
are only done if you bring an interface up online and never when already 
in running state.

But my memory may fail, sure....
