Logging SERVFAIL Errors

[Barry Finkel]

On BIND 9.7.1-P2 I have in named.conf:

     channel query-errors-log {
             file "/var/log/named.query-errors.log" versions 3 size 200k;
             print-category yes;
             print-severity yes;
             print-time yes;
             severity info;
     };

     category query-errors { query-errors-log; };  // no default_syslog

Is this correct for logging queries that produce SERVFAIL?

I ran this query on the DNS server:

dns# dig klyuniv.ernet.in @t1dns2.anl.gov

; <<>> DiG 9.7.1-P2 <<>> klyuniv.ernet.in @t1dns2.anl.gov
;; global options: +cmd
;; Got answer:

dns# 

and there is nothing logged in

     /var/log/named.query-errors.log

Am I doing something wrong?  Thanks.
