If a type=SLAVE domain has been removed from a master, and thus the SOA check returns rcode=9 or the like, the domain will be rechecked every slave cycle.

Worse, slave-cycle-interval (default 60 seconds) can be interrupted by many events for single domains, but the wakeup will cause this recheck for all failing domains. Busy slaves might re-check their failed domains every few seconds because of this.
