[Bug 1059286] Re: avahi-daemon takes 100% CPU right after boot

[Till Kamppeter]

As long as avahi-daemon is coupled with strace it behaves absolutely
correct. I can restart CUPS as often as I want and avahi-daemon does not
spin up. After that, independent whether I leave strace attached or not,
avahi-daemon continues behaving normally. Only if I restart CUPS while
strace is not cuppled to avahi-daemon, avahi-daemon spins up.

The problem seems to have started with CUPS 1.6.x which ships Avahi-
based Bonjour support from upstream in contrary to CUPS 1.5.3 which uses
a patch from Tim Waugh to implement Avahi-based Bonjour support.

Title:
  avahi-daemon takes 100% CPU right after boot and at every restart of
  CUPS

Status in “avahi” package in Ubuntu:
  New

Bug description:
  When I boot the system and log in avahi-daemon takes 100% CPU and
  Avahi/mDNS/Bonjour does not work at all, avahi-discover does not get
  access to anything and does not open its window, until it reaches a
  timeout and shows an error dialog.

  When I restart avahi-daemon with

  sudo restart avahi-daemon

  avahi-daemon usually gets back to normal not taking significant CPU
  percentage and answering to avahi-discover correctly. If it takes 100%
  CPU again I simply do another restart to get it to normal.
