- <question>
- <para>
- Can you help me understand how BIND 9 uses memory to store DNS zones?
- </para>
- <para>
- Some times it seems to take several times the amount of memory it needs to store the zone.
- </para>
- </question>
- <answer>
- <para>
- When reloading a zone named my have multiple copies of the
- zone in memory at one time. The zone it is serving and the
- one it is loading. If reloads are ultra fast it can have more
- still.
- </para>
- <para>
- e.g.
- Ones that are transferring out, the one that it is serving
- and the one that is loading.
- </para>
- <para>
- BIND 8 destroyed the zone before loading and also killed
- off outgoing transfers of the zone.
- </para>
- <para>
- The new strategy allows slaves to get copies of the new
- zone regardless of how often the master is loaded compared
- to the transfer time. The slave might skip some intermediate
- versions but the transfers will complete and it will
- keep reasonably in sync with the master.
- </para>
- <para>
- The new strategy also allows the master to recover from
- syntax and other errors in the master file as it still has
- an in-core copy of the old contents.
