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. |
