I've been having the same problem for about a week now. I've got
a script running that does a 'ndc reload' if nslookup doesn't get
a response for a few seconds. I've noticed some patterns around
my reloads in the logfiles.

  1. The logfile is quiet for serveral minutes. Normally
     I get around 75 messages per minute if logging noise
     like Lameserver and cname.

   2. Then I get several messages in the same second like
      ns_req: sendto(): Connection refused
      and in the mix, still the same second, I get occasional
      stream_getlen(): Broken pipe
      messages intermingled with the ns_req messages.
    
    3. Then usually a second later I see the reload message
       in the logfile.
