BIND process size

[Alexey Fadyushin]

Because DNS queries ahould be answered very quickly, ndmed tries to 
cache as many DNS records it learns from other servers as possible (and 
as limited by TTL fields in those records). So, the named daemon could 
stabilize using tens of megabytes of RAM. For example, on my servers 
after running for long time (months), it uses from 14MB to 37MB, 
depending on the number of zones it holds and on intensity of requests 
from its clients.

If you want to limit the amount of memory used by named, consider using 
the option 'datasize' in named.conf.
