Hi Michael,
This is a bug in the config parser in NSD, which is triggered by the
combination of a "*" in your include config element, chroot and
nsd-control reconfig.
The chroot directory was only removed from the include files location
after calling glob(). First time NSD reads the config there is no
problem because it didn't call chroot() yet.
A fix for this issue was committed to our repository on Oct 18.
Regards,
-- Ralph
