The same system, but using the kernel from unstable and not from
experimental does not show the messages, so they are related to the
experimetal kernel.
Does this tell anything?
root@apollon:/home/reinhard# lsof | grep netlink
dnsmasq 1862 dnsmasq mem REG 8,2 24712
7391593 /usr/lib/libnfnetlink.so.0.2.0
kded4 2839 reinhard mem REG 8,2 12272
9683029 /usr/lib/ntrack/modules/ntrack-rtnetlink.so
kded4 start after the first messages appear.
How can I find a program that runs every minute?
Reinhard
