Too many variables to tell. The first thing that breaks is normally the
limit of the total number of outstanding DNS requests. When that happens
depends on how fast and reliable the upstream servers are as well is the
incoming query rate.

Older versions of dnsmasq would spit out nasty log messages about
"forwarding table overflow" when this happened. The latest release both
allows you to increase the limit (--dns-forward-max) and handles hitting
the limit much more gracefully (it throttles incoming queries, rather
than dropping them.)


Cheers,

Simon.
