Hello,
on the big installations NSD can stop some secs/mins and "nsdc restart"
fail.
this patch for nsd.init fix this:
--- /etc/init.d/nsd 2012-04-09 18:01:39.446909907 +0400
+++ /etc/init.d/nsd 2012-04-09 18:01:24.248314446 +0400

# ensure notifies are sent at startup
rm -f $NSD_XFRDFILE
fi
+ while [[ $(pidof nsd) ]]; do sleep 1;done
echo
return $RETVAL
}
That's a nice possible infinite loop there.
What is taking so long for you? The "nsd patch" should be blocking,
so it is the actual "stop" that is taking so long? Is it a very
busy server?
That said, I do experience problems with nsd and rhel init
scripts too, where a "service nsd stop" won't kill nsd,
but I believe those are related to nsdc reloads and pid
changing, and nsd being unable to deal with the pid file.
