Linux still keep the expired prefix 15 seconds after its expiration

We have observed a behavior on our linux 2.6.20 box where the ipv6 address cannot be released 15 seconds after the prefix had expired. I have verified that addrconf_verify properly called ipv6_del_addr at the time of expiration. However, i am suspecting that the reference count of the address was not 0. Does anyone know of this problem? What could be possibly holding on to the address?
This linux box is connected to a router on an isolated network.
