The port numbers being the same should not matter to tcptrace. If you could
share us the dumpfile, I would have a look at it. You seem to be running
tcptrace version 6.6.1. There were a few bugs in it that got fixed in later
releases. Could you try and see if this problem still persists with 6.6.7?
If it does, please share us the dumpfile and I would have a look.
- Mani.
