Well, I don't know exactly what happens but I seems to be more complex
than I thought first. It doesn't happen each time I start tcpdump but when
some circumstances meet which I don't know my FreeBSD host begins to flood
the network with AppelTalk broadcast requests as long as tcpdump keeps
running. Killing tcpdump kills this flooding, too. I've never observed
such a situation before I applied the last patch, and I use tcpdump
frequently to analyze the one or other problem. On the other hand, our
network environment isn't static, of course, and I can't be sure about
other things that may have been changed from day to day.
