(1) when using DNSSEC, we strongly recommend upgrading PowerDNS to a 3.4.x release. Packages are available at https://www.powerdns.com/downloads.html
(2) it looks like your RRSIGs and KSK DNSKEY on the slave are truncated; we recommend increasing the size of the ‘content’ column in the records table (see our upgrade notes https://doc.powerdns.com/md/authoritative/upgrading/ )
