The internal implementation is more efficient, but is not yet as mature
as the external and might have problems to resolve some names.

A quite common reason to this is if the DNS server Squid is configured
to use is overloaded or performs badly. Usually due to lack of memory.

Other than this I have only seen all 32 being used when there is a
Internet meltdown and large parts of the net is unreachable.. See
http://squid.sourceforge.net/hno/ for a small patch allowing Squid to
handle the situation more gracefully (return an error to the client
instead of abort the whole Squid process).
