Hi, I have a lot of pcap files and I encountered this phenomenon several days ago, it will be a bit hard for me to find it now. When I see such a case next time, I will send it to you, thanks!

Version 1.6.6 should make a distinction between two sessions with the same ip/port combinations. Are you able to post the file here (if not to big) or else create a bug-report on bugs.wireshark.org? You can also mail me directly if you want to limit the exposure of the file.

Cheers,
Sake

Multiple handshakes wherein the same source & destination ports were re-used?
