Hi all.

I'm using unbound 1.4.16 with following server.
====================
FreeBSD9.0(32bit)
RAM 4GB
1 CPU
====================

unbound.conf:
====================
msg-cache-size: 250m
rrset-cache-size: 500m
module-config: "iterator"
====================

I checked cache memories using "unbound-control stats_noreset".
Increment of msg cache memory is stop at 266MB.
Increment of RRset cache memory is stop at 532MB.

But, increment of memory usage is not stop.
I checked it using ps command. The result is following.
==============================
# date ; ps aux | head -3

USER      PID  %CPU %MEM    VSZ    RSS  TT  STAT STARTED        TIME COMMAND

==============================
- Continuously incremented.
  But, not always. Sometimes this increment is stop.
- This increment is not synchronized with the number of queries.

Thanks.
