Pulled this out of my log.  Downloading lots of files through squid has
the download aborting after about 3k files.  This is the first I've seen
that there's also an associated ERR_DNS_FAIL -- is that a message from
squid's internal resolver?

One thing -- all the files were being downloaded in 1 copy of wget, so
it was
a long connection.

If I don't go through the proxy, it does download, but its hard to see
why DNS
would ahve a problem only 4 hosts are accessed in the download:


   1027 http://download.opensuse.org
      2 http://ftp1.nluug.nl
   2030 http://mirror.sfo12.us.leaseweb.net
     14 http://mirrors.acm.wpi.edu

3073...

    Looks like it's exactly 3k lookups and death on 3k+1

ring any bells?

Thanks
