Hello,
I am sorry, but since I got under pressure to stabilize our main
resolver operation, I had to downgrade to BIND 9.9.6 which effectively
solved the problem (i.e. even with max-cache-size set to 0 [unlimited],
the amount of memory allocated by named reaches certain maximum and
remains stable indefinitely).
The only info I can provide is the archive containing rndc stats from
the 9.10 period:
http://www.mujweb.cz/nakamura/dns/leakinfo.tgz
Sorry about that.

Meanwhile, please can you enable statistics-channels in named.conf and
send us a dump of the XML statistics along with process sizes reported
by ps when named grows very large?
I run the small script below every 5 minutes in a cron job
The result can be seen at http://ns4.jth.net/bind
There is no extreme memory leak running since Jan. 7th, but memory usage is
slowly increasing from
70 MB till now 161 MB.
In any case using 161 MB RAM serving 623 small authoritative zones and rarely
any recursive lookups
seems to me wildly out of proportion.
Disk space of zone files is 5,4 MB.
The developers of BIND ought to revisit the memory usage of BIND.
#!/bin/sh
# extracts the memory usage of named into a file
touch /var/www/html/jth.net/bind/bind_rss_history.txt
RSS=`ps -aux | awk '/^named.*named/{print $6 " " $5}'`
NOW=`date "+%Y-%m-%d %H:%M:%S"`
echo "$NOW $RSS" | awk '{printf "%10s%10s RSS %11sKb VSZ %11sKb\n",$1,$2,$3,$4}'
>>
/var/www/html/jth.net/bind/bind_rss_history.txt
GET "http://127.0.0.1:8053"; >/var/www/html/jth.net/bind/s`date +%F-%H-%M.xml`
exit 0
In named.conf the configuration is
statistics-channels {
inet * port 8053 allow { verytrusted; };
inet :: port 8053 allow { verytrusted; };
};
options {
zone-statistics yes;
};
