Stripping the number of resolvers unbound can use.

Unbound does not handle multiple resolvers well it internal 'logic' keeps
pounding and checking all resolvers making it a very slow process. By limiting
the count of resolvers it sould be more happy.

Count limititing is done using two-phase approch, firstly the initial resolvers
are limited to a fixed set of resolvers, secondly the list is updated based on
the results of the zone inquiries.

While here, ensure the listen is set on dynamic ranges ensuring failing
interfaces will not bring down the DNS server.

Making the list more limited and based on active resolvers.

  • Property svn:eol-style set to LF
