query-errors feature in bind 9.6.1b1 to troubleshoot SERVFAIL

[schilling]

Hi All,

We are experiencing some intermittent SERVFAIL issue even with popular
website like www.yahoo.com. So we installed the latest bind 9.6.1b1.
But we did not see any logs in /var/log/query-errors, is there
anything we are missing?

Thanks.


Compilation options:

[t...@test]$ /usr/local/sbin/named -V
BIND 9.6.1b1 built with '--enable-threads' '--with-openssl=/usr/local'
'--sysconfdir=/etc'

Run with -d2 according to ARM .

5 S root 30974 1  6  75   0 - 44613 -  11:06 ?
00:02:52 /usr/local/sbin/named -n 4 -d2

Change to:
severity debug 2;

 print-severity yes;
 print-time yes;
 };

 category query-errors { query-errors-log; };


Note that debug level 2 may be busy.
