BIND 8.1 Enhanced Features
BIND 8 Highlights
Resource Limits The server’s usage of many system resources can be limited. Some
operating systems don’t support some of the limits. On such systems, a
warning will be issued if the unsupported limit is used. Some operating
systems don’t support limiting resources, and on these systems a
cannot set resource limits on this system message will be logged.
Scaled values are allowed when specifying resource limits. For example,
1G can be used instead of 1073741824 to specify a limit of one gigabyte.
unlimited requests unlimited use, or the maximum available amount.
default uses the limit that was in force when the server was started.
See size_spec for more details.
coresize The maximum size of a core dump. The default is
default.
datasize The maximum amount of data memory the server may
use. The default is default.
files The maximum number of files the server may have
open concurrently. The default is unlimited.
NOTE 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, choosing 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 The maximum amount of stack memory the server may
use. The default is default.
Periodic Task
Intervals
cleaning-
interval The server will remove expired resource records from
the cache every cleaning-interval minutes. The
default is 60 minutes. If set to 0, no periodic cleaning
will occur.
interface-
interval The server will scan the network interface list every
interface-interval minutes. The default is
60 minutes. If set to 0, interface scanning will only
occur when the configuration file is loaded. After the
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 Nameserver statistics will be logged every
statistics-interval minutes. The default is 60. If
set to 0, no statistics will be logged.
