Hi list,

happy new year and stuff ;)

I'm in the progress of replacing some
old tinydns servers with unbound/NSD
primarily for built-in IPv6 support
and performance reasons.

It worked okay when I was testing it
from home with a single user. This
morning I put a little more load onto
it by integrating into our intranet
to do some tests before deploying it
for our customers.

This is where it started to signal 11
when queries began. Currently, there
are only IPv4 queries.

pid 569 (unbound), uid 59: exited on signal 11

This is reproducible so I went and did
a ktrace if that helps. I'm no coder
and I can't really make sense of that
output. If you need me to put this some-
where, just let me know.

BTW: is it normal, that the unbound pro-
cess is in the kqread state?

Any input on how to track this down fur-
ther would be appreciated. If any other
information is needed, just let me know.

Many thanks and best regards,

Sven Juergensen
