Explore /proc/$(pidof avahi-daemon)/fd/ and find out to what file or
other fd type all those open fds actually refer to. 

Histroic versions of Avahi didn't close all open fds on startup. So it
maybe some program is leaking fds when starting Avahi? I remember some
initng users having a problem like that with initng leaking fds like
stupid or something like it.
