RPZ zone load failure ran out of space

In the example below, when the length of bad.domain.com reaches 241 bytes, named-checkconf reports the following error:

“zone db.rpz.zone/IN: loading from master file db.rpz.zone failed: ran out of space
_default/db.rpz.zone/IN: ran out of space”

As per RFC1035, the DNS name maximum length is 255 bytes and each label length limit is 63 bytes.

I wonder what is the maximum length for bad.domain.com in the RPZ zone?

$ORIGIN rpz.example.com.
      $TTL 1H
      @               SOA LOCALHOST. named-mgr.example.com (1 1h 15m 30d 2h)
                      NS  LOCALHOST.

      ; QNAME policy records.
      ; Note: There are no periods (.) after the (relativised) owner names.

bad.domain.com      A      ; redirect to walled garden
                          AAAA    2001:2::1
