# avahi-daemon blocks nfsd on Ubuntu

I just spent a morning attempting to fix a NFS mounting configuration that had been working flawlessly for over 6 months. My daemon log was showing this:
nfssvc: writing fds to kernel failed: errno 98 (Address already in use)

After much angst, I finally stumbled upon this posting that mentioned a conflict between avahi-daemon and NFSd. After a quick "apt-get remove avahi-daemon", all is well with the world.
