http://www.zytrax.com/books/dns/ch7/hkpng.html#tcp-clients

tcp-clients
tcp-clients number ;
tcp-clients 20;

By default DNS uses UDP port 53 for queries but is defined to allow both TCP and UDP. The tcp-clients allows the user to define the maximum number of TCP connections to be supported. The BIND 9 default is 100. This statement may only be used in a global options clause.
