Confirmed in 11.1 gold.
It is not needed to change runlevels to trigger the bug, rcavahi-daemon restart
is enough.
It only happens when avahi-daemon is started as daemon ("avahi-daemon -D").
Starting avahi-daemon not in daemon mode won't trigger the bug.
Starting avahi-daemon with --debug doesn't give any useful information about
what it is doing.
After attaching gdb to a running daemon eating all CPU, this is the bt:
(gdb) thread apply all bt
Thread 1 (Thread 0xb7d078d0 (LWP 13947)):
#0 0xffffe430 in __kernel_vsyscall ()
#1 0xb7dcf63b in poll () from /lib/libc.so.6
#2 0xb7f34c1b in system_poll (ufds=0x806cd80, nfds=8, timeout=-1,
userdata=0x0) at simple-watch.c:619
#3 0xb7f34afd in avahi_simple_poll_run (s=0x8066970) at simple-watch.c:526
#4 0xb7f353d0 in avahi_simple_poll_iterate (s=0x8066970, timeout=-1)
at simple-watch.c:594
#5 0x0804efa7 in main (argc=2, argv=Cannot access memory at address 0xc
) at main.c:1078
And after attaching gdb to a running process in console (bug is not triggered),
this is the bt:
(gdb) thread apply all bt
Thread 1 (Thread 0xb7d738d0 (LWP 13972)):
#0 0xffffe430 in __kernel_vsyscall ()
#1 0xb7e3b63b in poll () from /lib/libc.so.6
#2 0xb7fa0c1b in system_poll (ufds=0x806c8c0, nfds=8, timeout=-1,
userdata=0x0) at simple-watch.c:619
#3 0xb7fa0afd in avahi_simple_poll_run (s=0x8066a58) at simple-watch.c:526
#4 0xb7fa13d0 in avahi_simple_poll_iterate (s=0x8066a58, timeout=-1)
at simple-watch.c:594
#5 0x0804efa7 in main (argc=2, argv=Cannot access memory at address 0xc
) at main.c:1078
There is no difference between both backtraces.
As a workaround, avahi-daemon can be started in the background as "avahi-daemon
-s&"
