Please share your complete dnsdist configuration, otherwise it's very 
hard to help you. The "sock_drop" counter from "ss" seem to indicate 
that dnsdist's incoming UDP buffers sometimes get full which is very 
unexpected at 1500 QPS, even without tuning, but without seeing the 
actual configuration it's impossible to know what's going on.
