Our nameservers take upto 10KQPS (mostly NOERROR type most of the time). Twice or thrice a week, I have seen upto 10% of the queries are SERVFAIL and we have started exceeding the default value of 2000 for recursive-clients settings in BIND 9.9.x.
Is there a recommended value for recursive-clients option assuming huge number of SERVFAIL queries once in a 2/3 days? I'm not convinced to increase it to some arbitrary huge number 20,000 or 200,000. I am looking for answer like - if your peak SERVFAIL queries are 2000/second, then your recursive-clients value should be N. Please help! thanks in advance Blr _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
