[Pkg-utopia-maintainers] Bug#693604: avahi-daemon takes 100% CPU right after boot and at every restart of CUPS

[Hagen Fuchs]

Package: avahi-daemon
Followup-For: Bug #693604

Hello,

I can confirm that applying the patch mentioned above[0] directly on the
Debian avahi-sources stopped these occurrences.  To be clear: Avahi
/never/ recovers from these load excursions and stays at ~100% until
killed.

In our environment of 39 print queues (about 30 physical printers) this
had become rather a serious headache with multiple daily occurrences.  I
wrote a rather desperate script that would minutely check for Avahi's
well-being.  After applying the patch about two weeks ago, it (the
script) recorded not one instance of permanent overload.

More tidbits: I have/had two servers exhibiting this behaviour (from a
total of four).  They multicast into different subnets.  One is a x86_64
KVM machine, the other a i686 OpenVZ container.  Also, the behaviour
occurs in heavily MacOS-infes...frequented subnets.

Thanks!

-Hagen
