bind 9.3.1 memory footprint

[majorboredum]

Hi all;

I am currently running 2 bind 9.3 1 caching name servers. Both servers
recieve about 700 -800 queries per second. Both servers are indentical
, running on solaris 9 .

I've noticed that one of the servers sits with a memory foot print of
about 750 mb. It stays there. Its stable.

Recently the other server has had its memory consumption grow about 2
mb an hr. I noticed it a few days ago when it was at 2 GB.

I restarted the server  2 days ago and its already up to 900 mb again.

I have not changed the max-cache-size or cleaning interval yet since im
not really sure if that would have any positive effect on the growth.
;

Does anyone have some ideas where to look for what may be causing this
issue? 


sincerely.
