ATM Traceroute middle packet loss?

This sounds a lot like the problem last year in MAE-East before
they upgraded to FDDI. A bug in *many* hardware implementations
dropped packets if the interpacket arrival time was too small (even
though the inbterpacket spacing was within spec.) I don't recall
anyone ever fixing the problem tho' It even affected several
sniffers so they would not see the packets, and hence not record
the drop....
