How about disabling enough links in your topology so that it doesn't have loops
and then trying? (I'm wondering if the second one has looped back to where it
started somehow.)
Another thought would be to wireshark all the ports of the switch where you're
seeing two of these packets. Do you actually see the packet arrive twice?
Leave twice? Etc.
