Folks,
From some lab testing it appears the answer to the above
question is NO.... but hope springs eternal!
We'd like to limit RAM usage by BIND (9.9.8/RHEL) on some
authoritative test servers. A load of configured zones would require over 10
Gig of RAM, but the boxes only have 4 Gig. We actually query only a few zones
for testing (response time is not an issue) and didn't want to do the work of
changing some standard zone lists and data we use.
Hoped we could set max-cache-size to something like "1000M" and
the server would load zones up to that limit in RAM. If it got a query for
another zone, it would bounce an "older" zone out of RAM and load the zone
needed for the query. Eventually the cache would stabilize. It appears
max-cache-size is just a resolver setting and BIND always expects enough memory
to load all cofigured zones to RAM.
On a larger test server I even tried setting "datasize 1000M" -
and that didn't seem to have any effect. BIND started fine and grew to about
10 Gig. Didn't expect that.
Appreciate anyone aware of a config setting that would limit
usage.
Many thanks!
John
