Dear Maintainer,
These lines appear in /var/log/syslog every 5 min
May 12 07:52:11 sleipnir NetworkManager[6719]: <info> Policy set
'Wired connection 1' (eth0) as default for IPv4 routing and DNS.
May 12 07:52:11 sleipnir NetworkManager[6719]: <info> Policy set
'Wired connection 1' (eth0) as default for IPv6 routing and DNS.
When it happens, eth0 gets another IPV6 address, for example:
eth0 Link encap:Ethernet HWaddr 00:0a:95:66:9c:38

This system was installed a few weeks ago. I believe I have made no
network configuration whatsoever -
just relying on standrad DHCP for IPv4 and Autoconfigure for IPv6.
I have one other Debain 7.5 system (an armv5tel system, not a PowerPC)
on the network, without this problem.
I have a very simple 6to4-configured OpenWRT router that advertises
the IPV6 network. The clients autoconfigure.
I also have several other computers with different operating systems
(Xubuntu, Mac OS X, Windows 7) on the
network - none of them have problems with several IPV6 addresses.
I noticed this problem because the avahi-deamon consumed 99% cpu when
I had almost 200 IPv6 addresses:
/var/log/syslog:
(almost 200 lines like the next line)
May 11 07:44:28 sleipnir avahi-daemon[2350]: Withdrawing address
record for 2002:XXXX:61ef:1:90d1:46d6:3b17:5f0a on eth0.
(then)
May 11 07:44:28 sleipnir rsyslogd-2177: imuxsock begins to drop
messages from pid 2350 due to rate-limiting
May 11 07:44:45 sleipnir NetworkManager[2174]: <warn> error monitoring
device for netlink events: No buffer space available
May 11 07:44:45 sleipnir minissdpd[3915]: recvmsg(s, &hdr, 0): No
buffer space available
I understand I may be better off without the avahi-daemon, but
switching it off does not fix the problem.
Restarting Network Manager brings me down to TWO IPV6-addresses (which
is one too much, as I understand it):
root at sleipnir:~# service network-manager restart ; /sbin/ifconfig
[ ok ] Stopping network connection manager: NetworkManager.
[ ok ] Starting network connection manager: NetworkManager.

According to syslog the problem appeared for the first time on 2014-05-09.
According to /etc/apt/history.log the system had not been updated
since 2014-05-01.
I updated it as soon as I found the problem, but with no success.
I belive the problem with TWO addresses has been present since I
installed the system. At that time
I just found it peculiar. But getting more and more addresses with
time is new since May 9.
This is an Apple PowerBook. The wireless network (eth1) is disabled.
The computer is on 24/7, acting as a test webserver.
Workaround: add to /etc/crontab
59 * * * * root service network-manager restart
Restarting the computer also takes me down to two addresses, but does
not solve the problem.
Below is standard reportbug output, run as root, otherwise I got
permission error with:
/etc/polkit-1/localauthority/10-vendor.d/org.freedesktop.NetworkManager.pkla
I find this all strange enough to file a bug report.
Thank you all for making a fantastic job with Debian!
Regards
Gunnar
