[Pdns-users] causes of over-capacity-drops

[mendisobal]

Hi, I use pdns-recursor (4.1.2-1pdns.xenial, Ubuntu 16.04.5 LTS), it serves 700 qps. Several times a day the over-capacity-drops counter increases to 12 qps at this time the concurrent-queries counter does not increase. Please tell me the reasons for this phenomenon and how to eliminate it.
