Well, if it works for other zones, it's unlikely to be an OS problem unless that zone was built in the system using an older version that did things slightly differently and now it can't be removed because of that difference. Have you tried comparing a working
zone that can be deleted from the problem zone with rndc zonestatus and rndc showzone? Maybe something will stand out there. But at this point, all I have to suggest is theoretical. Sorry, I don't know how to manually remove / rebuild the zone database.
If you're stuck after this and no one has any further suggestions, I'd recommend turning up the logging level on named and comparing operations or doing them under strace and seeing where success and failure diverge.</div>

<span style="font-size:12.0pt; color:black">There are a LOT of possibilities why this isn't working. The first two things I'd check is trying this action again as root (if you're not already) to make sure this action isn't trying something that's DAC prohibited
and checking the SELinux / AppArmor log (if you're running them) to see if this particular action (it doesn't sound like it's something you do often) is making a system call that's forbidden by the MAC.

haven't provided enough detail to determine that.</span></p>
