When PowerDNS is configured for a sqlite or sqlite3 backend and a slave zone is added, the PowerDNS daemon continually dies and respawns. This loop persists until the daemon is forcibly terminated.

My logs showed the following:

Cause:
The PowerDNS sqlite and sqlite3 backends do not support slave zones as of v.2.9.22

Resolution:
Configure PowerDNS to use a different database backend: MySQL, PostgreSQL, Oracle, etc.
