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.
