sup720 failover test

I am testing the failover speed on my 6509 with dual 720's. Using just a continual ping across vlans as soon as I do the failover command I see a slight delay but well within the advertised limits so that is good. However a minute or so later, I assume while the now secondary engine comes back to life I will get 2 or 3 timeouts. Can anyone explain what is causing this?

I've done the same test without the 2 or 3 timeouts. I would guess that it's your STP configuration. The links are coming back up and causing a reconvergence of STP....
