Hi Fred!

On linux 3.2.17, I have a host that configures IPv6 addresses on
an eth0 interface based on Router Advertisements received from an
on-link linux box configured as an IPv6 router and running radvd.
When the host gets an RA, it configures both an EUI-64-based IPv6
address and an IPv6 privacy address, so it has two IPv6 addresses.
But, if I leave the host up for long periods of time, it seems to
accumulate additional IPv6 addresses - perhaps these are stale
IPv6 privacy addresses?

Is this known behavior, and if so is there a way to turn it off?
Or, perhaps this was a known bug that has been corrected in more
recent linux kernel versions?

Could you send me the output of ip -6 a l?
