If you enable query log, you might be able to see if it's actually
serving queries at that time.
I mean "it hang" is named process is still running but it cannot
respond any lookup query. CPU is almost at low rate 5-6 % or lower.
It's both hang with single thread or multithread.
datasize is 9999m
max-cache-size is 2000m;
These are versions of bind i tried :
bash-3.00# file /usr/sbin/named
/usr/sbin/named: ELF 32-bit MSB executable SPARC Version 1,
dynamically linked, stripped
bash-3.00# which named
/usr/sbin/named
bash-3.00# file /opt/SUNWbind9.6/sbin/named
/opt/SUNWbind9.6/sbin/named: ELF 64-bit MSB executable SPARCV9
Version 1, dynamically linked, not stripped
bash-3.00# file /usr/sbin/bind
bind-9.7.1b1/ bind9.7.0P1/
bash-3.00# file /usr/sbin/bind-9.7.1b1/named
/usr/sbin/bind-9.7.1b1/named: ELF 32-bit MSB executable SPARC
Version 1, dynamically linked, not stripped
running 'named -V' is the best may to show version and configure options.
In my circumstance, i can try installing anything as long as it can
fix this bug. I saw on sunsolve there 's a patch for bind 119783-15.
Don't know is it useful to fix this bug?
No, that patch provides BIND 9.6.1-P3 with no specific changes.
Could you collect some lock statistics using plockstat(1M)? i.e.:
# plockstat -e 300 -p `pgrep ^named`
The -e 300 causes it to collect statistics for 5 minutes - experiment a
little and feed back what is reported.
Mb i will check with other version of bind. Hope this can help.

How did you determine that it "hang"?
If you enable query log, you might be able to see if it's actually
serving queries at that time.
Also, how is the cpu and disk usage at that time (I'm trying to see if
you have cpu or disk as bottleneck?
My guess is that:
- one of your CPU thread is at 100% usage
- named is busy serving queries alreadt, so that the new query you
issued does not get processed in a timely manner.

IMHO, it's not really named-specific problem. The thing is Sun/Oracle
T-series processors doesn't perform well with single thread loads. And
(last time I check anyway) even though bind can make use of multi
processor/threads, single thread performance still matters a lot.
So you'd probably get much better performance when running named with
say ... a generic x86 server/PC with Intel Xeon/Core i-series.
