Remove "max-cache-size" and if named grows to swapping, buy more
memory.  Make shure you have enough swap( i think AIX is
of the early-allocating type that allocates swap syncronously
with the application, thus you should have more swap then memory)

How big is named during the day ? Will it crash when it has
grown to soem specific size ? 

And check that "memory(kbytes) unlimited" means something more 
( there is a global maximum size that is configurable. ask
AIX folks what the limit is )
