zfs discuss - Nov 2006 - Zfs scrub and fjge interface on Prime Power

We have noticed that each time we initiate a scrub on our zpool , one of
the newtwork interface (fge1) on our PP650 goes down.
(always that interface, all others are fine )
If we cancel the scrub , a simple  ifconfig down and ifconfig up of the
interface fixes the problem !!!
When the interface goes down , no messages issued in  /var/adm/messages
!!
