(Hope you don't mind me posting back to the list.)

Anyway good guess, unfortunately I run it with the -n parameter... IP
addresses only, do not resolve names. :-(

Here's what it shows now:

Mem: 7548K Active, 1632K Inact, 5080K Wired, 536K Cache, 2477K Buf, 8084K Free
...
17609 root     28   0  1344K  1260K RUN      7:32  0.04%  0.04% tcpdump

Definitely growing.

Cheers.
