Hi all, I'm interested in how can I investigate in deep the throttled out queries. We have an open recursor due to business needs and during the last weeks we are answering a lot of SERVFAIL for random queries like web-127.com ..... (all of the forwarded to our abuse pool server)
From last service reboot I have this stats: (Recursor v 3.7.3) throttle-entries 390 throttled-out 344055 throttled-outqueries 344055 We received 2.291.374 of SERVFAILS on last 10 days. The server performance it's fine! But, we are receiving on syslog a lot of entries like : kernel: [21099878.651281] net_ratelimit: 153 callbacks suppressed We cannot be sure that both (SERVFAIL & kernel net_ratelimit) are related. Have anyone previous experience on this case? Thanks a lot.
