Well, I think you should be worried that your A-10 is somehow sending nonsense DNS packets to check liveness. Opcode 6 is not defined. https://www.iana.org/assignments/dns-parameters/dns-parameters.xml#dns-parameters-5 We'll make sure you can mute this warning with 'log-common-errors=no' in the future. For now, if this warning upsets you, you may want to ponder either putting dnsdist in front of your recursor to filter out opcode=6 queries, or (and this is likely better), replace the whole A-10 load balancer with dnsdist. Sorry we can't be more helpful, I checked, no one knows why the A-10 is sending queries with this opcode, or how you can stop it. Might want to ask A-10.
