Configuring and Administering the BIND Name Service
Configuring a Primary Master Name Server
Periodic Task Intervals Options: The periodic Task Intervals
Options are listed in Table 3-9 below.
file size_spec ; The maximum number of files the server may have open
concurrently. The default is unlimited. Note that on some
operating systems, the server cannot set an unlimited value and
cannot determine the maximum number of open files the kernel can
support. On such systems, specifying unlimited will cause the
server to use the larger of the rlim_max for RLIMIT_NOFILE and
the value returned by sysconf(_SC_OPEN_MAX). If the actual
kernel limit is larger than this value, use limit files to specify the limit
explicitly.
stacksize size_spec ; The maximum amount of stack memory the server may use. The
default is default.

Options Description
cleaning-interval
number;
The server will remove expired resource records from the cache
after the specified cleaning-interval minutes. The default
is 60 minutes. If set to 0, no periodic cleaning will occur.
interface-
interval number;
This specifies how frequently the server will scan the network
interface list (in minutes). If this is set to 0, interface scanning will
only occur when the configuration file is loaded. After he scan
listeners will be started on any new interfaces (provided they are
allowed by the listen-on configuration). Listeners on interfaces
that have gone away will be cleaned up.
statistics-
interval number;
This specifies how frequently the nameserver statistics will be
logged. The default is 60. If this is set to 0, no statistics are logged.
