Are you sure it is a BIND named on your system and not Solaris'
resovler with its own cache? ISTR Solaris had some sort of resolver
cache in its resolver library.

Anyway, if there is a signal one can send to BIND named to cause it to
flush its cache you could do that periodically, the periodicity
determined by watcing how long it takes to get to some predetermined
memory consumption.
