1. term1: tcpserver -v 127.0.0.1 8080 cat
2. term2: nc 127.0.0.1 8080
3. term3: nc 127.0.0.1 8080
4. fire up scope and look at process topology

Here's what it shows:

So the two nc are shown as being served by a single cat. In reality however each is served by a different cat. From the tcpserver logs...

tcpserver: status: 0/40 tcpserver: status: 1/40 tcpserver: pid 12972 from 127.0.0.1 tcpserver: ok 12972 :127.0.0.1:8080 :127.0.0.1::54590 tcpserver: status: 2/40 tcpserver: pid 13433 from 127.0.0.1 tcpserver: ok 13433 :127.0.0.1:8080 :127.0.0.1::54610

And running some lsofs...

matthias@xps:~$ lsof -i -a -p 12972 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME cat 12972 matthias 0u IPv4 2911228 0t0 TCP localhost:http-alt->localhost:54590 (ESTABLISHED) cat 12972 matthias 1u IPv4 2911228 0t0 TCP localhost:http-alt->localhost:54590 (ESTABLISHED) matthias@xps:~$ lsof -i -a -p 13433 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME cat 13433 matthias 0u IPv4 2914810 0t0 TCP localhost:http-alt->localhost:54610 (ESTABLISHED) cat 13433 matthias 1u IPv4 2914810 0t0 TCP localhost:http-alt->localhost:54610 (ESTABLISHED)

So it looks like the connection served by the 2nd cat (pid 13433) is incorrectly attributed to the first.
