I just test bind 9.5.0-P2 and 9.5.1-rc1
Bind 9.5.0-P2 allocate over 2Gb per 10 minutes of work.
Bind 9.5.1 allocate 2Gb per 30 hours.

i'm trying to run bind 9.5.0-P2 on a very low memory system.
It's a
RouterBoard 450 with 32Mb RAM running OpenWRT.
r...@sede:~# cat /proc/meminfo
MemTotal: 29920 kB
the problem is that bind seems to consume a LOT of memory ...
well,
a lot for low memory devices, i never noticed that on machines with
BS
of RAM.

question is .... is there something i can do to low bind's memory
usage and successfully run it on those very low embedded devices ???
Admittedly, BIND9 tends to require a lot of memory. I'm not sure if
it can reasonably function with a total system memory of 32MB.
Some related points:
- if you enable threads, disable them. With the thread support BIND9
will require even more memory.
- "max-cache-size 1048576" is a meaningless configuration:
Any positive values less than 2MB will be ignored reset
to 2MB.
(from ARM)
- 'rndc flush' doesn't release allocated system memory. It just
frees all cache entries within the BIND9 process, so it's not
surprising that you didn't see the memory footprint decrease after
the flush operation.
