As mentioned past queries that I can recognize and some that were

visit to few pages, ie. some activity there will be nothing.

The odd thing is perhaps - nscd should be good for local caching in just
such a situation (where something continually polls, e.g. in
javascript). When nscd is always passing the query upstream, it sounds
like whatever is being looked up isn't being found (default nscd TTL
for negative replies is 0).

Yesterday I grepped 'ps x' output for any 'kio_' and I found Konqueror using
kio_file, instead of kio_http, and DNS queries were back, so finally it is not
nscd as a source.

I just disabled IPv6, and I'll reboot after this message.
It could be the IPv6 DNS query that returns nothing, as my router just has not
clue what to do with it, that gives trouble to nscd. I'll see when I'm back.
