I am attaching an strace log. For this I restart avahi-daemon to assure that it is not on 100% CPU. CUPS is running. Then I run

sudo strace -ftvvs 65535 -p PID 2>&1 | tee log

with PID being the process ID of avahi-daemon. I have restarted CUPS at 23:58:50, then I have restarted CUPS at 23:59:31 and the restart command took until 23:59:38. I stopped CUPS at 00:01:24 and it took until 00:01:26. The log ends at 00:03:25.

Note that avahi-daemon did not spin up this time. It seems only to spin up if it is not coupled with strace. strace seems to slow down avahi-daemon and this way avahi-daemon does not go wild when CUPS is registering its print queues. After decoupling strace and starting cups again not under observation by strace, avahi-daemon spins up.

So we should run avahi-daemon under strace by default, simply piping the log to /dev/null ...

For me it seems a timing problem.
