Re: [squid-users] DNS processes running out

You either have a very high load, or your DNS servers is really slow.

If load is your problem, consider upgrading to a more recent Squid
version using a new improved internal DNS resolver (i.e. Squid-2.3 or
later), and don't compile Squid with --disable-internal-dns.
