Are the drops on all pools or just one pool? > I can stop this behavior only by restarting dnsdist.

I don’t find any infos in syslog I can recommend looking in the journal (journalctl -u dnsdist.service -n 40) and using the `grepq` and `topSlow` commands in the dnsdist console[1] and setting setVerboseHealthChecks to true in your config so dnsdist logs when a backend server goes down. 1- https://dnsdist.org/reference/config.html#grepq -- Pieter Lexis PowerDNS.COM BV -- https://www.powerdns.com _______________________________________________ dnsdist mailing list [email protected] https://mailman.powerdns.com/mailman/listinfo/dnsdist
