+Subject: [PATCH] Bound the amount of work performed for delegations
+
+Limit the amount of database lookups that can be triggered in
+fctx_getaddresses() (i.e. when determining the name server addresses to
+query next) by setting a hard limit on the number of NS RRs processed
+for any delegation encountered.  Without any limit in place, named can
+be forced to perform large amounts of database lookups per each query
+received, which severely impacts resolver performance.
+
+The limit used (20) is an arbitrary value that is considered to be big
+enough for any sane DNS delegation.
+
+(cherry picked from commit 3a44097fd6c6c260765b628cd1d2c9cb7efb0b2a)
